Here's an amazing vintage USC Trojans authentic wool letterman sweater made by Olympia Knitting Mills (a Wil Wite model) in Olympia, WA. It was sold by Silverwood's clothing store of southern California. This varsity gem is most likely from the '60s. This letter sweater is the real deal. It's a gorgeous, elegant, durable, and very thick button-up cardigan. It features two front pockets and a FELT SC patch. It is not very wide, but is long -- see measurements below.
This baby is in excellent condition -- no rips, holes, or stains. The colors are sharp. The wool is in tremendous condition and you can tell this sweater has been well stored and well taken care of. A couple small holes have been repaired at the top back.
