Woman in Stripes, Girl on Crutches, Looking Up at Animal in Tower, Vintage Glossy Snapshot

I always like a photo in which the subjects are turned watching some major or minor spectacle, all the better one taking place in a tower. I'm guessing we're at the zoo here, watching some sort of animal climbing up there, maybe a monkey. Most compelling to me is the combination of postures of this woman in her stripes, hands and purse on hip, and the girl beside her, leaning on her crutch. And then some horizontal stripes to counter the vertical ones of the woman's dress on the shirt of this young boy just making into the frame. 

4 13/16" x 3 13/16". Very good condition. Scalloped edge glossy photo, c. 1950s I believe.
