Must be the work of a nasty ex-wife. Any self- respecting HAMBer would wear that till it fell off him, then use it as a shop rag.
BA? Great find, wherever. My son, while in High School, found an old satin school jacket with stretch cuffs and collar snd "Bones" written across the back. Being 6'3" and skinny, it worked well especially since his High School car as a 57 Chevy BelAir 2door post car.
My Bardahl jacket disappeared in 1959 across the street from my High School auto shop. Some dork lifted it off my steering wheel! I had my name sewn in it, my Mom did that to all my jackets... Years later, I saw a Bardahl jacket hanging in the Disabled American Veterans' thrift store, looked it over...There was my name. Bought it for $1.50, hung it in my shop office. It disappeared again. LOL Same asshole, I'll bet...followed me for years, for that jacket...
You lucky......Stop by there and the pawn shop every few weeks and check for stuff like that, got a Tulsa Speedway 1991 Top Ten jacket in there once!
