Context paragraphs:
Peter Brown (Oz): Peter Brown is a major character in the Oz novels of Ruth Plumly Thompson, who continued the series of Oz books after the death of their creator, L. Frank Baum.  Thompson used Peter as the protagonist in three of her books: "The Gnome King of Oz" (1927), "Jack Pumpkinhead of Oz" (1929), and "Pirates in Oz" (1931).

Oz (comics): Oz is a comic book series created by Ralph Griffth (plotter), Stuart Kerr (scripter), and Bill Bryan, artist.  The series was begun by Caliber Comics.  It ran for twenty issues, six specials, and two three-issue limited series detailing the romance of the Scarecrow and Scraps, the Patchwork Girl, who create a child using the Powder of Life, in spite of Scraps's discomfort with the Scarecrow's new personality.  Jack Pumpkinhead was possessed and destroyed in the "Daemonstorm" company-wide crossover.  After twenty issues, the series was revived by Arrow Comics as "Dark Oz" for five issues, climaxing the story arc.  Nine issues followed titled "The Land of Oz" which presented a more orthodox vision of Oz, which was also shown in "Oz" issue zero.

Nome King: The Nome King is a fictional character created by American author L. Frank Baum.  He is introduced in Baum's third Oz book "Ozma of Oz" (1907).  He also appears in many of the continuing sequel "Oz" novels also written by Baum.  Although the character of the Wicked Witch of the West is the most notable and famous Oz villain (due to her appearance in the 1939 MGM musical "The Wizard of Oz"), it is actually the Nome King who is the most frequent antagonist throughout the entire book series.

Jinnicky the Red Jinn: The Red Jinn, later known as Jinnicky, is one of Ruth Plumly Thompson's most frequently occurring characters in her Oz books.  He was first introduced in "Jack Pumpkinhead of Oz" as a mysterious figure who educates Jack Pumpkinhead on the use of the Pirate Sack.  Although a detailed description is included in the text, "Jack Pumpkinhead of Oz" includes no illustrations of the Red Jinn aside from a gruesome color plate that did not appear outside the first edition, in which he has massive piercings.  He was reintroduced, drawn, and given the name Jinnicky in "The Purple Prince of Oz"; he also appeared in the follow-up, "The Silver Princess in Oz".  (He makes a cameo appearance in "The Wishing Horse of Oz", and he is the principal pre-existing character in Thompson's sub-canonical penultimate Oz book, "Yankee in Oz").  Jack Snow apparently thought the Red Jinn was a separate character, for he considered "The Purple Prince of Oz" Jinnicky's first appearance in "Who's Who in Oz", though he did not include a separate Red Jinn entry.

Jack Pumpkinhead: Jack Pumpkinhead is a fictional character from the Land of Oz and appears in several of the classic children's series of Oz books by American author L. Frank Baum.

Visitors from Oz: Visitors from Oz: The Wild Adventures of Dorothy, the Scarecrow, and the Tin Woodman is an unofficial sequel to the Oz book series.  Published in 1998, it was written by Martin Gardner and illustrated by Ted Enik.  It follows up after the last Oz book written by L. Frank Baum.

Yankee in Oz: Yankee in Oz is a 1972 Oz novel by Ruth Plumly Thompson.  It was the first published by The International Wizard of Oz Club.  A letter from the Henry Regnery Company, which bought Reilly & Lee, is reproduced in the front indicating the publisher's blessing for the new Oz book to appear.  It was originally written in 1959, but because the Oz books were not selling, it was not published.  The first two editions of the book were published in 8½ x 11 inch format and running only 94 pages.  This was done at the request of illustrator Dick Martin to reduce the number of required illustrations and to show them closer to the actual size they were drawn.  The second printing (1986) featured a new cover, with the first edition artwork reprinted preceding the title page.  The third printing (2007) is standard Oz book size.  Its cover is a gaudier redesign of the second edition cover.  The book also features maps by James E. Haff, and as such, Thompson correctly places the Winkie Country in the west of Oz.

Jack Pumpkinhead of Oz: Jack Pumpkinhead of Oz (1929) is the twenty-third of the series of Oz books created by L. Frank Baum and continued by other writers; it is the ninth Oz book written by Ruth Plumly Thompson.  It was Illustrated by John R. Neill.

John Dough: John Dough was a common name for a gingerbread man at the turn of the 20th century, though the best-remembered John Dough is the character created by L. Frank Baum in his 1906 novel, "John Dough and the Cherub"; the character also makes a cameo appearance in Baum's "The Road to Oz".  If the fragment known as "An Oz Book" is genuine, Baum may have intended to include John Dough in his fifteenth Oz book had he lived to write it.

The Purple Prince of Oz: The Purple Prince of Oz (1932) is the 26th in the series of Oz books created by L. Frank Baum and his successors, and the 12th written by Ruth Plumly Thompson.  It was illustrated by John R. Neill.
