He has more then 150 limited edition lithographs and collector prints plus over fifty limited edition collector plates to his credit. There are also scores of incentive and special commission art products on the market bearing his name. Thousands of collectors worldwide enjoy his work. Admirers and peers alike are always looking forward to the new projects that emanate from Derk’s Saddle Tramp Studio. Derk has managed to stay as elusive to the public, as some of the wildlife he so beautifully represents in his work. If you are looking for him, you will not find this artist in the main stream of the art world. A cattle drive, working horses in the round pen or hanging out with his cowboy friends playing his guitar, is more his style. One day he might be in Africa on safari doing fieldwork for new paintings or you might find him working on a documentary video in the rugged mountains of New Zealand. Then again, you could find him studying bald eagles off the wilds of Alaska or researching for a humpback whale painting off the island of Hawaii.
