Help with artist?

I recently purchased some items and need some help identifying what I have here. I have searched the name on the pictures and found this site with an artist named Willie Yazzie. While this is obviously not the silver Jewlery he is kown for, they share the same name. Can anyone help me out with what I have here. I actually have 3 pictures. All of them are originals, looks like acrylic possibly, but Iā€™m not sure.

Any help or direction would be appreciated :slight_smile:
