This is for a Vintage Frisch's Big Boy 10K Solid Yellow Gold Supervisor Employee Pin featuring the Big Boy character with Striped Overalls and a Slingshot in his back pocket. It has the Big Boy in a running pose carrying a large Big Boy hamburger. This real solid gold pin is about 3/4" tall and 5/8" wide and weighs 2.3 grams. The back of the pin says G.B.M. & Co. 10K Cinti, O.

I got this Frisch's supervisor employee pin from someone that had a job at the first Frisch's in Cincinnati which was the Frisch's Mainliner on Wooster Pike. This pin is from the 1950's I believe as I found this newspaper article but can't make out the exact year from the picture. It looks like it might be 1952.
