Antique Sepia Toned Rattlesnake Photograph

I can't imagine encountering a rattlesnake and doing anything other than quietly backing away, but some brave soul managed to take this photograph long ago. It was mounted on card, and then much more recently someone taped it to cream paper, from which is is easily removed. I really like how closely cropped the the image is--just barely containing the snake and amplifying a sense of immediate danger! 

Photograph measures 2 7/8" x 1 3/4". As mounted: 6" x 4".  Very good condition.
