I came accross this beer can today while detecting in the woods. When I picked it up I thought it was just another 70s era ring pull can, but when I turned it over I noticed there is a modern bar code printed on it. I've never seen an old ring pull can with a bar code on it. I scaned the bar code with my phone, it took me to a vintage bar code site then eventually it did ID the bar code as from Stroh's Beer.
