Pictured above is a hand-drawn ink concept drawing of a vehicle - Mace Bomber. Literally thousands of these pen/ink drawings were made between 1982 and 1994 by Hasbro designers - a select few were turned into toys. These unproduced concept drawings are a fascinating look at what didn't make it to toy shelves.

Note the Hasbro Confidential logo in the lower left hand corner.
