This series contains a variety of loose design concept drawings and two bound sketchpads. Only some of the illustrations are labeled, signed, and/or dated.

Information on specific folders and the sketchpads is included below.

•There are 3 large unfinished sketches for the Atari Leisure Time Game Center concept, with one drawing for an Atari Theater Kiosk. •There is one sketch of what The Strong has identified as Gran Trak 10. In the same folder, there are 10 drawings of Trak 10 cabinet designs. •Within the “2 Game Module” folder are 10 drawings. There is one sketch of a cabinet labeled with both Trak 10 and Gotcha, while another page depicts a cabinet holding Trak 10 and Rebound. The remaining concepts are not labeled. •Atari never produced a game called Dodgem. The 3 pages of design concepts in Folder 8 may have been applied to another arcade game project. These were signed by Regan Cheng. •There are 6 sketches in the folder for TX-1; three of these are signed by Stephen Pombo, who likely made the remainder. •Folder 10 holds 13 pages of different concepts for cocktail table-style, or tabletop, arcade cabinets. •Folder 11 (miscellaneous design drawings) contains 23 sketches, with representations of Barrel Pong, Gotcha, Demo Derby, Gremlins, Peter Pack Rat, Air Race, and other unlabeled cabinet concepts. •The first sketchpad, sized 19” x 24” and located in Box 1, does not have a specific artist’s signature. The 26 drawings in this volume also comprise various cabinet and component designs, with notations for 4-Player Football and Red Baron. •The second sketchpad, found in Box 2, likely belonged to Regan Cheng. Within this 14” x 17” pad are 42 pages of various cabinet and component designs. Games labeled include Pin Pong, Qwak!, and Quadrapong. This volume also holds several concept sketches for the proposed Atari Leisure Time Game Centers (also shown in Box 1, Folder 5).
