Found this while helping my friend move out, apparently from his grandpa’s beer stash from the 70’s. Some great Simpsons jokes came up. We did vote for the wrong Carter. 😉
Billy Beer was a beer first made in the United States of America in July 1977, by the Falls City Brewing Company. It was promoted by  Billy Carter, the younger brother of then-President Jimmy Carter. The beer was produced by Cold Spring Brewing, West End Brewing, and Pearl Brewing Company.
Quotes on the can:
Brewed expressly for and with the personal approval of one of America’s all-time great beer drinkers – Billy Carter.
I had this beer brewed up just for me. I think it’s the best I ever tasted. And I’ve tasted a lot. I think you’ll like it, too.
