Troy Denton Indian print

This print from Advanced Graphics, Martinez CA features Indians on horseback. I obtained it from auction, therefore I have no background information. My research found his works to be very valuable with a wide array of pricing. It seems his works are in as much question as his existence is/was. Many place high value on his paintings. I was wondering if this print has any value? My 80 year old mother in law has Indian heritage and simply loves the print. Either way it is then valuable to me.
