1:4 Scale The Astronomy Textbook opens and has 35 pages with 20 technical illustrations. It measures approximately 2 and 3/4 inches high by 1 and 7/8 inches wide. The title is prominent on the spine so it will look GREAT open or closed.
All of my books interior paper, hardcover book board covers, ink and glues are acid-free archival quality. As you can tell from the photos most of my books are readable. Perfectly scaled for your 42cm tall or about 16-18 inches like Toner or American Girl size dolls or larger dolls. One book can take 2 or more hours of graphic design and research of copyright.
This is a collectors item and it is not recommended for small children.
