This is a nice minty treasure for sure, see pictures! This came from a Chicago attorney's closet back in the 70's and I believe he may have been involved with the can in some legal respect but I can't know for sure as he has passed away, but he had numerous product containers in his closet that looked like they never held an actual beverage, soap etc.
Please see pictures for details of condition. I do not see any issues but there may be small pock marks that I missed, etc. But they would be very minor.
