Variety of Non-Postage Stamps (1950s)

I picked these up recently at my favorite antique shop in Port Orchard, Washington -- Olde Central Antique Mall -- for a couple of bucks. They were just too fun to pass up. I particularly liked the Alcoa food labels, but the 1958 Publishers Clearing House stamps are pretty nice, too. Enjoy -- or click through for full-sized scans.
