Patent illustration Valentine’s cards

Steve Hoefer whipped up these fabulous print-at-home Valentine’s Day cards with particularly romantic patent illustrations. He writes:

For a maker Valentine’s Day is no Halloween. Or even Christmas. In fact on the list of holidays makers get excited over Valentine’s Day is near last, right between Leif Erikson Day and Flag day. And while those are all fine traditions, bu they rarely get people all excited about making stuff for them.

So, in an effort to turn that around I present, straight from the United States Patent Office, Maker Valentine’s Day Cards.

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.
