Just spent some time researching American Toy Theaters at the The United States Patent and Trademark Office. You can also search at Google’s patent section. If you like research this is fun! I found so many wonderful paper toy patents from the late 1800′s to the early 1900′s. Patents make great wall art and are fun to work with in digital and paper collage. If you like Steampunk (like I do) this is a great resource for inventions at the turn of the 20th century. Keep in mind, not all patents can be used. The illustrations etc. may also be copyrighted. Please read further info on this at The United States Patent and Trademark Office.
