Included in this lot is a framed Yellowstone National Park Ranger Naturalist Service poster. This poster displays a depiction of Old Faithful going off with an orange blue sky in the background. The top of the poster says "Ranger Naturalist Service; Nature Walks, Field Trips, Camp Fire Programs, Nature Talks". The bottom of the poster is marked "Yellowstone National Park U.S. Department of the Interior National Park Service". The bottom left is marked in small red letters "Copyright 1995 Doug Leen". The poster is set into a painted blue wooden frame. The piece is in good condition, showing no signs of damage. The frame measures 19" by 25". The piece appears to be a wood block solid print.
