1971 golf print information?
 

Not sure if this is the correct place to post this or not. My wife picked this up for me at a yard sale thinking it was baseball. It's golf and i have no clue what it is. The back is numbered. Mine is #642.

The signature on the print is Walt Spitzmiller and the picture says 1971 Ryder Cup St Louis Missour and has Walter Hagen and Samuel Ryder. Says RYDER 50 years.

Any help is greatly appreciated
