These images come courtesy of the tasting room at the Harpoon Brewery in Boston, Massachusetts. In the middle of a tour of the facilities, guests are invited to sample as much beer as they can drink in 20 minutes. They really kept us busy sampling, so most others there probably don’t notice the massive collection of beer cans lining the back wall. When they announced it was time to exit and finish the tour, I straggled behind a few seconds to capture some of the most interesting/obscure cans.
