I'm a part time collector and a full time scrounger. I scour local auctions, antique stores, flea markets for first quality goods.
For my personal stash, I collect Daguerreotypes, Ambrotypes, and Tintypes. Sometimes in order to get just one photo, I have to buy a big lot. Anything that's not prime I get rid of on eBay, but the good images go on here.
