Young Brunette Girl Undresses Her Jeans At The Window

Riveted jeans
Dry goods merchant Levi Strauss was selling blue jeans under the "Levi's" brand to the mining communities of California in the 1850s. One of Strauss' customers was Jacob Davis, a tailor who frequently purchased bolts of cloth from the Levi Strauss & Co. wholesale house. After one of Davis' customers kept buying cloth to reinforce torn pants, he had an idea to use copper rivets to reinforce the points of strain, such as on the pocket corners and at the top of the button fly. Davis did not have the required money to purchase a patent, so he wrote to Strauss suggesting that they both go into business together. After Strauss accepted Davis's offer, the two men received U.S. Patent 139,121, for an "Improvement in Fastening Pocket-Openings," on May 20, 1873.
