Need help figuring out what all this stuff is - South American items

[TJNDND]

Hi,

My grandmother collected arrowheads and other Native American items, but also was very interested in the Mayan culture. She lived in Texas around the 1920's and collected various items in her travels to Mexico and the Mayan sites over the years (1920-1930). She left me about 7 boxes full of this stuff, but I have no idea what any of it is, or if it's real or made for tourists. My assumption is that it's a combination of the two. Below are a few pictures. I will post more as I unwrap everything. Thanks for any help anyone can provide!

Thanks,
TJ
