Antique Photograph of Jockey (?) with Great Face and Shadow

I assume based on his outfit and especially those striped sleeves this fellow is a horse jockey, and perhaps it is the wall of an old stables he is posed against, cigarette in one hand, hat in the other, and casting a great shadow. I really love his face, and his hair, and his pose, and can imagine he was quite a character. 4 5/8" x 2 3/4". A small crease/fold mark at upper left corner; overall good condition.
