Native Hopi Blanket

This is a hand woven blanket that the tag says it from the Hopi tribe. It looks to be rather old but I am not sure. If anyone could authenticate that it is Hopi, it would be greatly appreciated. Also, does anyone know the age or value of this blanket. It isn't that big and is about three feet wide and two feet tall. There are two wooden poles threaded through the top and bottom of the blanket. Please help me with any information about this piece.
