Brickskeller Endangered Species Beer Cans

 

Here are (4) Brickskeller endangered species beer cans from my collection.

 

From what I can tell these were made in and around 1977 by the Pittsburgh brewing company.  There were two series of twelve cans in each series - yellow and blue cans.  Unfortunately, I have only two from each set:

Houston Toad, Texas Lone Wolf, Leatherback Sea Turtle and Colorado Squawfish
