March 11, 1929. Mr. Ernest E. Quantrelle, 15 Broad Street, New York City. Dear Mr. Quantrelle; Yours of February 26th with the photograph of the new watercolor received. Under separate cover, I am returning the photograph. If, some time you are willing, I would be happy to have a copy of it, just to keep a record of where some of the good pictures are. The picture represents a bunch of Blackfeet sighting a wagon train for the first time. Both horses and men are excited and curious. You can fairly hear that pinto horse whinny and the foremost Indian is making the sign of “See!” They look like a bunch of trouble hunters but they are looking for their redskin brothers and not the white invaders. These redmen are not conscious of what that wagon train means to their country. The back-ground looks like the Judith country with Square Butte and Wolf Butte in the distance. I’m happy that you own that watercolor. It is fine and will always be a pleasure to you. “Good Medicine” is coming along fine and I can hardly wait to see it in it’s covers. Kindest regards to Mrs. Quantrelle and yourself. Sincerely, NCR:ED
