The case is the hard outer shell of a book, what's under the jacket. Case designs can vary, but often they repeat the name of the book both on the front panel and on the spine, either debossed or in foil or pigment stamp. But I prefer to shake things up, putting illustrations or design elements from the jacket or interior on the case. Little Easter eggs, if you will, for a curious reader. Here's my latest and most ambitious: Illustrations by the incredibly talented Spencer Charles. Actual printed stamp pic TK soon!
