If you know what an Artograph is, you probably are an art teacher or an old-school graphic artist, and you know whether this device would benefit you or your students. It's a DB 300, principally designed as a drawing-board projector with a 3x enlargement or reduction, or 18x on a vertical surface. It weighs 40 pounds, uses two 150-watt photo enlarger lamps and pulls 115 volts and 3 amps. We have the original owner's manual. Free to a user who can make good use of this great teaching aid.
