French Secret Compartment Book

A little stack of old books, one of which has a secret cavity inside.

This secret compartment book bound in leather is from France, and dates to the 20th century. It is leather & bound paper. France has a long tradition of fine bookbinding, and leather bindings with gilt lettering were produced there in large numbers. Bound volumes with ridged spines and rubbed gilt tooling, standing and lying together. One book lies open to show a square pocket carved out of its pages, with the text block gone yellow at the edges. It is 6 inches wide, 2 deep and 8.25 high.

Never judge a book, unless it is hollow.
