Native American Indian Head Figure Wall Art Set of 3 Head Dress 1991 Plaster

Beautiful set of 3 Native American Indian head figures for hanging on a wall. The largest measures approximately 8x5.5 inches, the medium one measures 5.5x4 inches and the small one measures 3.5x3 inches. The small one is marked 1991 on the back. I am not sure if these are from the same set. They feel like they are made out of plaster. Please see photos for specifics and condition. Feel free to message me with any questions or if you would like to see more photos.
