15x15-5/8" artboard w/attached onionskin/paper overlays has original mixed media art depicting the main box lid art for Lindberg model kit No. 291. 1971. Art is unsigned and depicts grotesque one-eyed monster w/dart-like tongue wielding a spear and mace against a green/blue/black gradated bkg. From a series of glow-in-the-dark monster model kits by Lindberg, this model kit features the same figure as "Zopp" from Lindberg's "Lindy Loony Repulsive" series from 1964. Image area measures 11.25x12" and margins have printing labels/notations. Overlays show wear but art remains NM and would look stunning framed.
