Chicago Safety Sticker - Put Waste Here - 1960's ?? 1970's ??
This is one of three Chicago Safety Board safety stickers I recently picked up. Not sure of their vintage, but they styling I'm going to guess is 60's or early 70's.
Now, vintage SAFETY stickers are not the thing I would have thought I'd be interested in, but I saw these and something about their color and design I found really compelling. So I had to have them. Now here they are for y'all.
