Pop-up book partially coincident with children's book
While it can be documented that books with movable parts had been used for centuries, they were almost always used in scholarly works. In 1775 Thomas Malton, the elder published A Compleat Treatise on Perspective in Theory and Practice, on the Principles of Dr. Brook Taylor. A Compleat Treatise on Perspective is the earliest known commercially produced pop-up book since it contains three-dimensional paper mechanisms. The pop-ups are activated by pulling string and form geometric shapes used to aid the reader in understanding the concept of perspective.
It was not until the very late 18th century that these techniques were applied to books designed for entertainment, particularly for children.Some of the first three-dimensional and tab activated books were produced by Ernest Nister and Lothar Meggendorfer. These books were popular in Germany and Britain during the 19th century.
The great leap forward in the field of pop-up books came in 1929 with the publication of the Daily Express Children's Annual Number 1 "with pictures that spring up in model form". This was produced by Louis Giraud and Theodore Brown. Four more Daily Express Annuals followed and then Giraud setup his own publishing house, Strand Publications, this produced the groundbreaking series of Bookano books. The Bookano books are considered the first, true pop-up books for children because the pop-ups can be viewed from a full 360 degrees, not just the front side facing the viewer. There were seventeen Bookanos before the series came to an end with the death of Giraud in 1949.
In the United States, in the 1930s, Harold Lentz followed Giraud's lead with the production of the Blue Ribbon books in New York. He was the first publisher to use the term "pop-up" to describe their movable illustrations.The next advance in the field was made by the astoundingly prolific Vojtěch Kubašta working in Prague in the 1960s. His lead was followed by Waldo Hunt in the US with his founding of Graphics International. He and two companies he established, Graphics International and Intervisual Books, produced hundreds of pop-up books for children between the 1960s and 1990s. Although intended for US audiences, these books were assembled in areas with lower labor costs: initially in Japan and later in Singapore and Latin American countries such as Colombia and Mexico.  Hunt's first pop-up book was Bennett Cerf's Pop-Up Riddle Book, published by Random House as a promotion for Maxwell House Coffee and showcasing the work of humorist Bennett Cerf, who was then president of Random House. The team of Waldo Hunt and Christopher Cerf created a total of 30 more children's pop-up books for publication by Random House, including books that featured Sesame Street characters. According to Bennett Cerf (in his book At Random), pop-up books were profitable for Random House.In addition to his collaborations with Christopher Cerf at Random House, Hunt produced pop-up books for Walt Disney, a series of pop-up books based on Babar, and titles such as Haunted House by Jan Pienkowski and The Human Body by David Pelham.
