I had the good fortune to meet Ismar David a couple of years before he passed away and thoroughly enjoyed learning more about the design of his signature "David" typeface from him. Now, the wonderful Misha Beletsky has put together a short monograph on his book jackets. It includes a short essay on the history of book jackets, and a short bio of Ismar David that puts his exquisite calligraphic work in context. The sum total is a lovely diversion and a welcome addition to my bookshelf (although I anticipate sharing it widely, so it may not be on the bookshelf when I go looking for it).
At $19.95, the book is quite modestly priced. It is available from RIT Cary Graphic Arts Press and other fine vendors.
