Any body seen these glasses before??

I thought it was too good to pass up when I saw them, and figured they had to be rare. They don't look like they've been used much if at all (they are dirty inside as if they were on display for years) and I don't plan to use them for anything but display as they are just too cool. I too was guessing late 60's early 70's based on the logo and the style of the glasses.
