There was a Fleet out of Norcross, GA that was acquired by Ashland in 1967. There was also a Fleet out of LaFollette, TN that was later rebranded to Peer. Don't know if this can is related to either of those companies or not. Information from Henderson/Benjamin's Guide To Gasoline Logos.
I collect gas pump salt and pepper shakers and the plastic coin banks made by AVSCO.
