These items were not available for sale to the public and have been stored away since the D23 exhibit was dismantled. I am so very grateful to Alice for thinking of me when granted access to the LU props. Below is video of the LOST University dorm room I found on youtube. The pillow can be seen on the bed, and the pennant is one of several on bulletin board.
