The game of golf wouldn't be what it is today had it not been for 4 fundamental inventions. Commemorate these achievements every time you take a sip using a pint glass engraved with a piece of history: the United States Patent and Trademark Office details of golfing equipment. Choose one of 4 pint glasses that showcase the patent information of a specific piece of golfing gear: ball , club , tee , or caddy bag . Every glass is engraved with an invention's issue date, document number, and representative drawing. Designed for golf enthusiasts, history buffs, and beer lovers, each 16-ouncer shines a spotlight on the level of detail and amount of engineering that goes into a seemingly simple piece of sporting equipment. Made in Massachusetts.
