Try to find the spot where the photographer was standing.
I gotta say, this photo got me wondering ... is golf enough of a "sure thing" that the only way to gamble is on buying golf balls? ;)
Turns out, (thanks to Google) this is a 1938 Mills Golf Ball Slot Machine - 25¢ made by Mills Novelty Co. during the late 1930's and early 1940's. Sold directly to upper end golf courses, these machines would payout in golf balls rather than money.
Mills modified the cabinet of one of their existing slot machines to hold golf balls and dispense them at the bottom. With the use of an electric motor, the appropriate number of golf balls would come out on winning plays. It has a wood cabinet with hand painted green trim. —Nation's Attic
Indeed it is. I was interested too and just found a little news article on Trove about golf balls and a slot machine with fifteen pounds cash being stolen from a Melbourne golf club in 1939... nla.gov.au/nla.news-article11238607 I suppose it was a novel way to lose a bit of money!! EG
And here's a color colour photo of a restored, but original "golf machine":
fantastic picture !
