Has anybody ever seen this picture, or have any idea of it's origin?

I have it on a Blum's Bulletin supplement, but it's the only Blum's supplement I have that doesn't have a caption, which seems kind of strange since the numbering of the players in the picture seems to allude to a caption listing the names matching the numbers.

Any help is much appreciated, thank you in advance,
Doug
