Vintage boxed souvenir ashtrays Indian woman on horse

Amazing that this set is still in it's original box with lid. This set of 4 glass ashtrays are a souvenir from Flagstaff Arizona. Each of the ashtrays are identical and have a picture of a Native American woman on a horse. Each ashray measures 3" in diameter and has a green felt back. Original price on the box shows where the set brand new, once sold for $1.50 at some gift shop. Selling as a set.Like new, and I don't think they have ever been used.
