Vintage Men's Bowling Shirt

Vintage men's polo bowling league shirt made by Hilton. It is black with 4 buttons in the front. The name Yukio is on the front in white felt or fuzzy letters. What I am guessing is the last name, Shimizu, (part of the u has come off, making it look like an i) is on the back in the same white lettering. The team was for Sumitomo Bank in Stockton, California in the 50s-60s. Size small. Measures 19.75 inches pit to pit. Great condition, found at an estate sale in plastic hanging in the closet.
