An exceptional Italian sideshow box with inside a teratological specimen of a 2 headed calf.

But what make it even more special is the document of the veterinary (Giacomo Caffa) stating that the calf born on 24 rd of February 1939, with a unique body. "The milk cow is in good health ... and she's ready to give birth to another calf ..."

And a very nice paint on wood of the calf with his mom complete this masterpiece of folk art, that probably was show during the town festivals, just before the II World War.
