This must bring back some memories for some older folks.
A-1 beer was a product of the Arizona Brewing company from 1933, when brothers Martin & Herman Fenster founded the company, until it was bought out in 1964.
They used the eagle in their logo from 1942 until 1958 when Anheuser-Busch forced them to remove it, claiming it was too similar to their own. So the fact that this sign includes the eagle makes it between fifty-seven and seventy-three years old. Not only has it survived this long, but at night, the neon still glows!
A really interesting history of the company can be found at
