This is a LVC 501xx 1937 model W36, made with current organic cotton. This 1937 model is popular as a set-up with the tracker 1st and s506xx wartime models, which are worn by famous celebrities and YouTubers. The 37 model is gaining popularity along with the wartime and 1st models. Are you looking for one? When you think of Levi's, you think of the red tab! This 1937 model is the first model with the red tab. The pocket flasher and hidden rivets also first appeared on this 37 model. And the single-needle arcuate (where the stitching doesn't cross in the middle) is the last model for the 37 year, and the inseam rivets are also the last for the 37 model. In many ways, this 1937 model is a commemorative piece. In 1937, the winds of the Great Depression raged, and the 501 continued to evolve, blending the old and the new. Around this time, Levi's iconic red tab was invented, and the back style was completed to differentiate it from other companies. The waist still had a cinch back, the suspender buttons, which were becoming obsolete, were removed, and belt loops, which were becoming more common, were added. And, in response to customer complaints that the exposed rivets would scratch furniture and saddles, the back pockets were sewn in a way that hid the rivets (hidden rivets). To emphasize the hidden rivets, the world's first pocket flasher was also invented. It's getting closer to the familiar, impactful, and persuasive packaging we see today. How about this reproduction model of the 501, which walked alongside the people of San Francisco, who never forgot to look forward in difficult times?
