“507” model jacket Detail of “507” model jacket

Levi Strauss & Co. debuted its denim jacket in 1905, giving it lot number 506. In 1953, it introduced a second jacket model, known as the 507, seen here. Present on both versions (after 1936) was the bright red “LEVI’S” tab. Created at the height of the dude ranch era, the recognizable tab branded Levi’s® products so that they could be identified at a glance.
