From the details and design, it's likely from the 1960s. ※ Although the clasp isn't visible in the image, I will provide the one I have. ※ Other accessories that match the riders jacket are also on sale. 【Size/Color】 Approximately 1.3 x 1.1 cm Silver with blue rhinestones #SilverWhich? ← Check out silver items!!! #BlueWhich? ← Check out blue items!!! 【Condition】 The pin is slightly bent, but there's no problem with attaching it. Other than that, there is some distortion and rust, but it has good details unique to vintage items♪ 【Remarks】 Although there is no certainty, based on the design and the PBL notation: P (ROFESSIONAL) B (OWLING) (LEAGUE) I believe it's from the Professional Bowling League.
