Here is an incredible $2 dollar thrift store find.  Extremely rare 1942 Lee Cowboy "War Time" jeans.  This model was produced for about 1 year.  Beautiful in every way to the denim connoisseur. Some of the details are: crotch rivet, Lee center tag, single needle tailoring, "Lee Cowboy" donut top button w/ plain blank zinc following down the fly, lined inside back pockets, and half selvedge along outseam to cuff.  The most iconic aspect is the use of the "Reverse Arcuate" on the back pockets. Basically a Levi's arcuate flipped upside down.  Recently reissued by Lee Japan. I estimate 30-40 original pairs exist around the world in private collections.  This pair was sold in 2006 For $3000+.
