Diego Rivera Art?

I found this piece at an antique shop. So far after months of searching, I can not find another like it.  The paintings on it do resemble the works of Diego Rivera, a famous Mexican painter.

I have an arts dealer helping me in my search and I may come up with nothing, but I may come up with something.

Time will tell..  Have you ever seen anything like it?

I believe it made of a teak wood.. its a goat. cow
