This is a pretty amazing piece done by an accomplished high school artist back in 1976.  He obviously idolized the player and it shows in the emotion of the painting as well as the artistry of the frame which he repurposed an old tennis racket almost 50 years ago with a reddish purple wash.  He even made a backing and hanger for it. I was struck when I entered his bedroom, still kept by his parents just as it was 50 years ago, filled with tennis items and this hanging above his bed.  A really cool vintage piece for the tennis fan!
