When I first started publishing these historic prints Yellowstone National Park wouldn't carry them so I finally went to Hamilton Stores who were the concessions at the time for the previous 88 years. John Grieve, one of their principal buyers, gave me display space in four of his top stores and we sold $60,000 worth of prints in that park in three months the following summer. I later went back to the park (different stores than the concessions') and asked again if they would carry the posters in the NPS bookstores and they refused me again. I argued that I was a former ranger (Grand Teton) and would prefer to see these profits go directly to the NPS. Finally I toured these stores and found one single box of note cards on the shelf with Fort Marion as the top card (of a mixed set of 8 which included Yellowstone Falls). This last box was way on the back of the shelf and out of sight so they didn't perceive they were out of product (they carried only my note cards, not the posters). The sales person didn't know even what these images represented. At the cash register was a big bowl of toe rings (rings that you put on your toes). I thought this was inappropriate material for a park bookstore and that my silk screen reproductions of the historic art of that park, originally made by the WPA, no less, was a better product than toe-rings. Still to no satisfaction--and then informed them that the NPS has a duty and an obligation to educate the visitors about their parks. These toe rings in my opinion were the same thing as cheap rubber tomahawks that you used to buy in the 1950s during the early TV westerns rage. Ditto for turkey feather headdresses which were cheap off-shore (usually Japan) imitations of what once was a noble item of dress for the American Indian. I told the park if they didn't raise their standards, I was going to print bumper stickers and plaster them on cars in NPS parking lots, much like the "Sea Lion Caves" obtrusive advertising. The rest was history--of course, I didn't put these on cars but began sending these out to all my customers as a tongue-in-cheek reminder that the NPS needs to keep their quality up. We, at Ranger Doug's Enterprises are the only ones to offer these WPA national park reproductions in silk screen and find them a perfect fit for NPS bookstores to interpret their parks. Many of the internet knock-off "artists" are printing these on on-demand printers and the like. Some are printed in China (Shanghai) on cheap paper; one even includes the lifted Department of the Interior seal which is a federal (and proprietary) seal. Big Bend National Park actually approved these Chinese/Seal versions. About 10 years ago, I came up with a red, white & blue American flag with "Made in America" on it and within a week, one competitor (who prints in Shanghai) put a front page notice up on his website about how of every dollar spent on their products, $0.85 stays in the US. What that really means is that he prints/ships for only $$0.15 and doubles his selling price six times! You may read that notice here: http://www.impactphotographics.com/MadeInUsa.asp This is a bunch of hooey! So in short, these are simply reminders to the parks to keep their standards high and stock our quality, hand-made (in the USA) screen prints. Oh, and they are extremely popular on the Indian Reservations.
