Most gearheads are curious about how things work. I know I am. That’s why Gadgets, Games and Gizmos is such a fascinating book to me. It’s full of original drawings that were submitted to the patent office for some of the most iconic products of our time and the past. What’s in there? The paperclip, ball-point pen, umbrella, space suit, Polaroid camera and more. It covers 122 inventions that changed the world and makes for a great book to have on the counter, coffee table or back of the toilet. You can get it now from Amazon for $19.
