For people like myself who love collecting (and using!) vintage ephemera, I think trading stamps rank right up there in items to collect. I have always loved them, even though they were pretty much gone by the time I was old enough to know what they were. I do remember a couple of S&H places around Green Bay, but as far as redemption centers there, I think they were all closed in the 70s.
Here are just a few samples from my collection:
I've also made others with just one or two stamps - they're so versatile! Anytime I need a small space filled on a collage, I almost always think of these trading stamps first. Just like postage stamps, they're little works of art in and of themselves. And because I love anything and everything to do with vintage supermarket and grocery store ephemera (that's a whole 'nother blog entry!), they fill that niche as well.
How about you? Have you made any art with trading stamps? I'd love to see - just post the link in the comment box! :D
