Rear projection screen fits into briefcase
Any projectorâ€”movie, slide, filmstrip, or microfilmâ€”can be used with this miniature fold-up screen. The “black” Plexiglass screen is eight inches square and can be comfortably viewed by six people. The Groupshow Mini’s folding hood keeps room lights from washing out the picture.
