After the party I met up with a different group and we checked out a large antique mall just across the River.
That's where I found this 50th anniversary special edition American Can can from 1984 for $2.50. I have a few other special edition cans like this. And it had an interesting pull-tab top on it.
A little while later I found a Diet Coke can I don't have. But I really didn't want it. I left the hip can with headphones and sunglasses there. Maybe next time, haha.
