Wear your book on your sleeve! Or, maybe better, the lapel of your jean jacket.
Ideal Bookshelf was able to capture the essence of a book in less than an inch square.
Each badge is a hard enamel lapel pin with raised gold-plated outlines. It's about 1 inch tall by 0.75 inches wide, and attaches to your clothing with a black rubber clutch.
Based on an original drawing by Jane Mount.
