These are Remington prints from Collier's Magazine and were mass-produced for resale, created circa 1906 to 1912. They were offered in the magazine by mail order for about $1.00 each, and often re-printed in different sizes, also grouped in folios with titles such as "Remington's Best Paintings." These were marketed as Artist's Proofs, a term that deceivingly suggests that these were prints pulled first from the press for Remington's approval. The "Artist's Proof" tags also have a simulated Remington signature, another factor that fools the untrained eye.
These prints have a current value of $20 each retail, so it would be $120 for the set of six framed prints.
