Native American Art Deco

This is the same building I blipped a few days ago, (not sure how to link back, can someone help me with that please?)

There are 4 of these Native American heads along the top front of this building, I'm sure hardly anyone passing by would even know they were there, you really can't make out what they are from the ground, 12.5 floors down, but zooming in they are really impressive.
