I am not used to such humorous Dover titles. When this showed up in my Little Free Library, it caught my eye. I don't recall the last time a book made me laugh out loud so often! An automatic whip, spectacles for chickens, combination cheese gator mousetrap.... The self-tipping hat I had seen before, but all else were new to me.
Very amusing compilation of patents. Each entry contains the original patent information and a drawing. Garnered a lot of insight into what was considered important in earlier years.
It's like a less-interesting 1930s version of 101 UN-Useless Japanese Inventions. By 1930s I mean it came out in the 1930s; the inventions are much, much earlier.
