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. 293. 1971. Art is unsigned and depicts grotesque bug-eyed monster w/wide gaping mouth and four sharp teeth against a purple/black gradated bkg. From a series of glow-in-the-dark monster model kits by Lindberg, this model kit featured the same figure as "Voop" from Lindberg's "Lindy Loony Repulsive" series from 1964. Image area measures 11-1/8x12" and margins have printing labels/notations. Overlays show wear but art remains Exc. and would look stunning framed.
