Question: How many books were illustrated each Christmas for eight years by the man who, along with Walter Crane and Kate Greenaway, was among the strongest contributors to the child's nursery motif for during the 19th century? 
Context: That Pesky Rat is a children's picture book written and illustrated by Lauren Child and published by Orchard UK in 2002.  It won the Nestlé Smarties Book Prize in ages category 6–8 years and it was commended runner up for the Kate Greenaway Medal from the professional librarians, recognising the year's best-illustrated British children's book. Edmund Evans (23 February 1826 – 21 August 1905) was a prominent English wood engraver and colour printer during the Victorian era.  Evans specialized in full-colour printing, which, in part because of his work, became popular in the mid-19th century.  He employed and collaborated with illustrators such as Walter Crane, Randolph Caldecott, Kate Greenaway and Richard Doyle to produce what are now considered to be classic children's books.  Although little is known about his life, he wrote a short autobiography before his death in 1905 in which he described his life as a printer in Victorian London. The Copeland House is important as an example of a vernacular farm residence built in the Carolina back country after 1790, along what would in the early 19th century become an established coach road from the coastal counties to the interior.  Constructed in the late 18th century by John Jacob Copeland (1775-1853), it became the center for his family that grew to include eight children.  The house and the nearby farms, many belonging to families related by marriage over time, became significant contributors to a German Lutheran settlement in the area which took shape in this part of South Carolina a generation before the start of the American Revolution.  The nearest town, Ehrhardt, South Carolina, is about 2 miles east of the Copeland House.  The residence, initially built in the early 1790s, is significant for its association with the Copeland family, who built the house, occupied it continuously and farmed the surrounding property for nearly 200 years.  In the mid-1980s the Copeland descendants, heirs to the fifth generation of the family, sold the property.  The original square log and dovetail construction remains largely intact, even after several significant 19th and early 20th century modifications and additions were made.  Subsequent owners have generally maintained the original fabric while stabilizing the structure.  The house, together with several related dependencies and an adjacent Copeland family burial site, was listed in the National Register of Historic Places on October 18, 1991. Randolph Caldecott ( ; 22 March 1846 – 12 February 1886) was an English artist and illustrator, born in Chester.  The Caldecott Medal was named in his honour.  He exercised his art chiefly in book illustrations.  His abilities as an artist were promptly and generously recognised by the Royal Academy.  Caldecott greatly influenced illustration of children's books during the nineteenth century.  Two books illustrated by him, priced at a shilling each, were published every Christmas for eight years. Helen Gillian Oxenbury (born 1938) is an English illustrator and writer of children's picture books.  She lives in North London with her husband John Burningham, another children's book illustrator and writer.  She is a two-time winner and four-time runner up for the annual Kate Greenaway Medal, the British librarians' award for illustration.  For the 50th anniversary of that Medal (1955–2005) her 1999 illustrated edition of "Alice's Adventures in Wonderland" was named one of the top ten winning works. Edward Jeffrey Irving Ardizzone, {'1': ", '2': ", '3': 'CBE RA', '4': "} (16 October 1900 – 8 November 1979) was an English painter, print-maker and war artist, and the author and illustrator of books, many of them for children.  For "Tim All Alone" (Oxford, 1956), which he wrote and illustrated, Ardizzone won the inaugural Kate Greenaway Medal from the Library Association for the year's best children's book illustration by a British subject.  For the 50th anniversary of the Medal in 2005, the book was named one of the top ten winning titles, selected by a panel to compose the ballot for public election of an all-time favourite. Walter Crane (15 August 1845 – 14 March 1915) was an English artist and book illustrator.  He is considered to be the most influential, and among the most prolific, children’s book creator of his generation and, along with Randolph Caldecott and Kate Greenaway, one of the strongest contributors to the child's nursery motif that the genre of English children's illustrated literature would exhibit in its developmental stages in the latter 19th century. The Cranesville Historic District is a historic district in Dalton, Massachusetts, centered on the business and residential proprerties associated with the papermaker Crane and Company.  Papermaking began as an industry in Dalton in the early 19th century, and was dominated by Zenas Crane's operations by the early 1820s.  Crane and Company controlled numerous papermaking operations throughout the Berkshires, but it was headquartered in Dalton, where the Crane family lived.  The Cranesville area, running along Main Street in Dalton, is dominated by the large homes built by various members of the Crane family over the years, as well has more pedestrian mill worker housing.  The historic industrial facilities of Crane are also included in the district, although they are generally screened from view from Main Street.  The most notable of these facilities is the National Historic Landmark Crane and Company Old Stone Mill Rag Room, the oldest surviving building on the Crane premises.  Of the Crane family homes, those of Zenas Crane and Winthrop Murray Crane (Zenas' grandson and a major political figure in Massachusetts during the turn of the 20th century) have the most prominent positions on Main Street, near the industrial complex. Simon Bartram is an English illustrator and writer of children's picture books.  He was one runner-up for the Mother Goose Award in 1999 for "Pinocchio" and for the Kate Greenaway Medal in 2002 for "Man on the Moon: A Day in the Life of Bob".  In 2004 "Man on the Moon" was voted "best illustrated book to read aloud" by a panel of "Blue Peter" viewers and also named Blue Peter Book Awards Book of the Year. Under the Window: Pictures & Rhymes for Children (London, 1879) was Kate Greenaway's first children's picture book, composed of her own verses and illustrations.  Selling over 100,000 copies, the toy book was a commercial success, helped launch Greenaway's career as a children's book illustrator and author in the late 19th century as well as starting what became known as the "Greenaway vogue".
