Over time I have purchased copies enough of this book to be certain I have one always close at hand in the house and out in the Mellow 60s Museum. This was my first typewriter book, the first of many, and it was a great help when I began to collect typewriters. The photos are excellent, and the supporting text invaluable. Curious about typewriters? Thinking you might collect typewriters? Already hooked on typewriters? For each degree of interest, Rehr's wonderful book will be a must-have. A section on typewriter ribbon tins and another on antique calculators and more, also very well photographed and described (with rarity rankings for tins), will add greatly to readers' enjoyment.
