1890 XX501® JEANS
90501-0009 • MADE IN USA • D1 • RIGID
To the owner of this 501® Jean,
While Levi Strauss and Jacob Davis invented the blue jean in 1873, 1890 was the
first year the 501® lot number was adopted. Levi Strauss & Co.’s patent for riveted
clothing expired that same year, meaning that other companies could now also
use rivets on clothing. To answer the coming competition, LS&Co. printed the
inside pocket bag with information about the strength and originality of the
1890 was the year that the 501 number was first assigned to the famous pants–
likely done because the company no longer had an exclusive patent, and also
because it had a good-sized line of clothing by this time. It was easier for retailers
to order their products by number rather than by a simple description, as had
been done in the past. Any product made with the highest quality materials was
given a lot number beginning with 5: 501 for the overall, 506 for the jacket, etc.
Made with XX 9oz denim from the Amoskeag Manufacturing Company, the 501®
pant was at the head of the class.
