Up for your consideration is a vintage 1970s Stroh's Beer Sign. It is almost 18 and 1/2 in Long by just under 12 in wide.
It is made out of a thin plastic over foam board. It doesn't look like the sticky was ever used. It does have some cracks and a few holes. But for its age and what it's made out of, it's held up quite well. I can't find any others for reference.
Back in the time when it was legal to drink at 18, the sign has a nice smiley face on the top letting you know that they would gladly serve you if you're 18.
Please look over the photos as what you see is exactly what you will receive.
