Origin of this iconography, birds, fish on glasses

These are silver resist / overlay glasses with figures that I think should be from somewhere specific but I'm not sure where. Most of the silvered glasses I'm finding have very traditional patterns, not so tribal looking.

I did find a set of glasses with somewhat similar designs that the seller was saying were Mexican but without any qualifying information. Many Mexican glasses have very heavy silver that looks very different.

Do they look familiar to anyone?

 

Aleut?

Don't seem detailed enough for Mayan

Only guesses.

 

I'd started out thinking North West Native so I agree with what you're thinking however I'm not seeing much that looks similar. I'll look a bit more then probably just use them myself.

 

Not Northwest Coast.....or any NA native.....that I know of !

 

I think Aztec, dumbed down a bit. Have a look at some of the ones here: http://imgarcade.com/1/aztec-bird-symbol/
