The book of Illustrations of Sexual Devices from Patents Applied for at the United States Patent Office

This book is intended for an adult audience. I'm an illustrator and designer. While doing some research for a patent application project I came across some patents for sexual devices. I found the illustrations so entertaining I spent some time collecting as many as I could find. I have included in this book the ones that I found interesting and, or laughable. I think you'll have fun just trying to decipher what some are intended for. Others will amaze you that anyone ever thought that getting a patent on their concept was a good idea. Many I included for the quality or lack of quality the drawings possess. As an illustrator both entertain me. These are all from the United States Patent Office and a matter of public record. Some include dates, most do not. The oldest one I found was from 1908. Here we go, just for laughs.
