Miniature Monolith model featured in the Star Trek: The Next Generation episode "Masks". This "clean" version of the monolith that appears in Councilor Troi's quarters does not feature the alien symbols on the side, and was created by the art department for use in the episode. Made from a dense foam this piece features a rock like finish and is accompanied by a set of production material including an original shooting script and notes. Item measures 18" tall, and comes from the collection of Ronald Moore.
