Posted this on Classic Funny Car Forum and two replied indicating the decal in question is Anderson Industries:
Anderson Industries (AI) made fiberglass bodies back then, below is the small excerpt From the HAMB web site.
"Most of the glass companies from the 60's are long gone. The few that are still in business include VFN in Addison, IL. Hairy Glass and US Body Source in Florida and my old company Rod 'n Race which is the old Anderson Industries (Ai Fiberglass) now located in Hagerstown, MD."
