I have one of those, too
Re: the "He Makes a Wise Choice who drinks here." I have one of those Vanguard 1970 wall plaques, too. I just bought it in Ardmore, Alabama at the Dog Days Flea Market for $20. The bottom right corner is broken off but I was so enchanted by the graphic of the owl holding a beer stein I bought it anyway: it now sits in front of my laptop and the broken corner doesn't show, so I'm very pleased to have it in my possession. I also wondered what it might be worth. I'm guessing it must have hung in a bar or pub somewhere at one time.
