Sighted on Core77, a new exhibition at Art Center’s Williamson Gallery on the rarefied world of patent models. “‘Up until 1880, if you had a brilliant idea, something that you thought would change the world, and you wanted to get patent protection for it, you had to submit a working scale model to the government,’ says Stephen Nowlin, vice president of Art Center College of Design in Pasadena. Nowlin is hosting an exhibit called ‘The Curious World of Patent Models,’ a traveling show organized by the Rothschild Patent Model Museum, which will reveal more than 50 artifacts submitted for patents way back in the day.” In honor of America’s Independence Day holiday, we’ve chosen six of our favorite scale models — each no larger than 12 inches square — from the collection.
