I love researching these old fairy tale illustrations! There are 2 tiny accordion-fold books on this sheet. Plus 6 tiny postcards, and 3 characters from a Cinderella paper doll set.
The books fold up to a finished size of 1-1/2" wide x 1-3/4" tall (a bit big for 1:12 scale, unless you think of them as coffee table books). Or buy the sheet as a digital file and print at half scale for a truly 1:12 scale book.
The books will (just) fit behind the cover of the Cinderella Coach Mini Album. I'd suggest you first paper over the back of the mini coach album cover so that you'll have images that show through the cut-out windows (or maybe make a pocket to hold the booklet — either way back the accordion book with thin paper or paint).
NOTE: since these are teeny tiny, the printed version of this sheet is on a lighter weight 24 lb laser stock (the normal 80 lb stock is just too heavy to fold)!
