Pictured below the Sunbow/Marvel video of the mini-series, The M.A.S.S. Device. It was released through Family Home Entertainment (F.H.E.). The back of the box features a short comic strip summarizing the episode. Note the error on the back cover, as Flint is pictured, but does not ever appear in this cartoon.
