Strange looking things

My brother showed me a couple of items that were the strangest things I have ever seen.  

 

This kind of looks like something from the Mayans era. Could this be a god of some sort?  I am curious to know what this is exactly.

 

It almost has a animal looking nose, huge ears and what is it holding?

 

This is a stamp with a primitive handle on it.  Do you think that it could be a monogram stamp from centuries before?
