The little girl riding this beautiful pony is very adorable. She is plainly dressed and wearing high socks and sandal type shoes. She is likely not an equestrian, judging by her clothing. The little girl and pony were photographed by W. J. Nolan & Company in Cambridge, Massachusetts. Preliminary research found other photographs by the Nolan firm that featured children on the same pinto as seen in this photograph. Apparently, Nolan liked to use the pony as a prop in his photographic work. (SOLD)
THE CABINET CARD GALLERY 
According to my mom, some businesses would go around with a horse for photographs.
I am enjoying the fact that both the pony and the child have their bangs cut in the same style of fringe!
I have a delightful photo of my mom, about age 5 years. sitting on a similar pony, with fancy western tack and a cowboy hat on her head.
She has a huge smile.
Her brother was photo’ed too, separately.
This pony belonged to an itinerant photographer who cruised around taking such photos. Those were the days…..
