Large Plaster boy figure bank

If anyone has ever seen anything like this before please let us know,  or even if they can identify the style of dress the boy is in.  The only I dentifying mark we can find is mexico carved into the stump of the tree.  The entire thing is hollow and has a slit on the back of the boy to put money in.  The lady that gave us this stated that it was in her grandmothers house ever since she was a child.  So I am guesing this weas made in the 40's but I could be way off. 

If anyone can tell us anything about this we'd be ecstatic. 

Thanks

Good
