Vintage photo of unfazed child riding two headed calf

I love how unfazed the child in this photo looks while sitting atop a two headed calf. The kid looks deep in thought, like they have completely forgotten about the mutant cow beneath them. Imagine another kid asking if the kid in the photo has a rocking horse to play with, but the taxidermied two-headed calf is what they're presented with. I'd love to know the backstory of this photo.
