It's a very lovely rendering, and quite tasteful.
I believe that perhaps subliminally, Tommy was inspired by the June 14th, 1971 Sport Illustrated article, "The Ghosts of Merion" where hovering specters of great players like Hogan, Armour, etc., who won and lost across that great course, were superimposed atop pictures of the holes where the most dramatic of their feats occurred.
I don't have a scanner here, but perhaps some others have the magazine, as well, and could post a few?
