This is an original concept design drawing created by Disney Imagineer Clem Hall while working on EPCOT at Walt Disney World. Hall created imagery for use in the American Adventure attraction, Space Mountain, Bit Thunder Mountain, and the various world pavillions at the WDW and Disneyland theme parks. This particular drawing depicts imagery that looks to be from the development of the American Adventure with a scene from Pilgrims sailing on the Mayflower. The piece measures 18" x 23" overall with the main image area measuring 11" x 17". The piece is in overall very good condition with edge wear that would be expected in concept art that is being handled by an artist, and part of the imgaery created on a separate sheet which was taped to the main sheet.. There are two additional smaller detailed drawings used by Hall while working on individual elements of the drawings as well, as seen in the last two pictures.
