Picked up my first thrift store cufflinks today. There was a pretty large donation of vintage ones, and I picked up the ones I liked most.
Back row: Swank, Hickok, Unbranded (but has patent number for to clasp, which I think makes it 1940s-1950s)
Front row: Unbranded, Taxco sterling silver
I've done tons of research to try to educate myself on vintage cufflinks, with a little luck. The two in the front row are probably the best...
