The "Pop-up" Mother Goose. With "Pop-up" illustrations in full color by Harold B. Lentz (New York: Blue Ribbon Books, Inc. [c1933]).

Students of children’s literature, illustration history, and historic book structures consult works like this classic edition of Mother Goose. As is common among early children’s books, the volume has damaged covers, loose pages, and a number of tears, especially at the vulnerable (and delightful) pop-ups.

Proposed treatment: Check pop-ups and mend where necessary. Remove old spine and reline, restoring pages to proper alignment. Add new acid-free hollow and new paper spine. Remount original spine on top of new one. Touch up color of worn covers and board edges.

Estimated cost of treatment: $900
