The first three formats of this series include the same three titles with different over-sized covers.
The second format books are 9.5 x 7 and have a book appropriate appliqué (paste-on) on the front cover. They originally came with very hard to find dust jackets. Publication date is unclear but after 1922.

Today I am adding book #3 The Little Small Red Hen to the database. It is pictured below with the other books in this format.
