Vintage pin B.P.A. MO. Brooch Gold tone Pin MOBPA bowling bowler

Vintage brooch with a heart and faux pearl charm hanging from a pin engraved "B.P.A. Mo." I think this stands for the Missouri State Bowling Propietors Association, but I'm not positive! It's in pretty good preowned condition with some surface wear and patina, but nothing major. Measures approx 1 7/8" long. Ships fast! SUNC828QL6G4E bowl bowler jewelry
