Decade
The last Big E years. Levi's replaced the hidden back-pocket rivets with bar tacks around 1966 and switched to the small e tab in 1971, the Type III jacket arrived and Wrangler moved to broken twill in 1964. Lee's Riders now had a black waistband tag, and the Storm Rider name was on its lined ranch jacket.
