Finding beer cans at yard sales is only slightly unusual, but finding one of these beer cans at a yard sale is VERY unusual. The former owner of this can was selling a tub of fairly recent commemorative Coke bottles and beer cans. After my inquiry about older cans elicited the “brake fluid” response, I ended up in his basement, and the rest, as they say, is history. 🙂
Here’s a link to the Brewery Collectibles Club of America. The club is always looking for people who enjoy scouring the countryside for these kinds of hidden treasures.
