Unfortunately (perhaps fortunately) I was too young to drink alcohol when these came out during the 1970s They were quite iconic and looked like a small beer keg almost - athough what they were was a larger than life can. Much like a heinz soup can, only full of beer! You would make a hole in the top of the giant tin can and another to let the air in, and then pour the beer! Very 1970's camping trip. It got it's name because apparently you could get 7 pints of beer out of them - however, from what I've heard the beer also tasted vile.
