Vintage “Golfer’s Prayer” Gilded Mug

This vintage white mug has gilt edging, a very slight pedestal and a Golfer”s Prayer on a bordered yellow background that reads “May the good Lord grant ‘fore golfing days are done that I might just once score a legitimate HOLE in ONE.” 1612 is stamped on bottom. This piece was displayed and not used-it shows. Beautiful vintage condition-no stains or cracks/Last 2 photos show a manufacturing flaw on the bottom rim & a dark spot on back (I don’t know what this is)
