Pictured above: Some more vintage finds on eBay. If you like looking at vintage clothes and ever want to kill an hour, just dig around eBay’s “completed listings” section. I filter for “sold listings” and sort everything according to the highest prices ended. That way, I can see what serious collectors recently fought over. Useful terms (at least for the kind of stuff you see above) include: Buco, motorcycle club, car club, motorcycle jacket, bomber jacket, flight jacket, WWII jacket, USN jacket, vintage varsity jacket, etc.
