What better way for a maker to celebrate Valentine’s Day than with a celebration of romantic inventions and innovations from times past complete with illustrations.

The cover of each is an original, amusing, Valentine’s Day themed US patent that I’ve restored for high resolution printing. Inside are matching cheeky (and occasionally suggestive) Valentine’s day comments. The back features a short description of the patent.

Feel free to download, share, and print the PDFs below. They are for 8.5 x 11 inch paper (5.5×8.5″ cards) but can be resized easily. I’ve left the inside as a separate PDF so you can add your own wittier or more heartfelt turn of phrase.
