Vintage Photograph of Beautiful Crouched Boy

I can't quite discern enough detail on this boy's shoes to determine the age of this photo, but I might guess 1940s or so. What drew me is how balletic he looks--while I assume he is posed as if about to launch into a sprint, to me he looks much more on the cusp of becoming a Merge Cunningham dancer, with the sensitive, soulful face to match. To my eye, quite a lovely and poignant image. 

4 7/16" x 3" and in good condition, printed on a what looks to me like a matte finish photographic paper.
