Project + Patent is a line of graphic t-shirts inspired by original patents of ubiquitous, seemingly ordinary objects.
The Slinky patent t-shirt is another one of our popular old school designs. History buffs and trivia geeks may know that Slinky was patented on January 28, 1947. Others will only remember Slinky as a fun-it's-a-wonderful toy, not to mention fun for a girl and a boy. Whatever the case, you and others will enjoy this shirt.
The shirts are all hand silk screened on 100 percent cotton soft tees. Charcoal shirt with pale yellow ink.
Unisex, S, M, L, XL See size chart. Free domestic shipping $50 or over
