This series holds 24 pages of drawings showing various designs for the arcade game Gauntlet (also noted as “Project 443” on these documents). Nearly all of these sketches were stamped with an “Atari Coin-Op Division Industrial Design” emblem, and designer Ken Hata filled in the name and dates on these papers.

These full-color design concept sketches include illustrations of assorted cabinet styles, control panels, speakers, angling of monitor screens, cabinet dimensions, assembly, and more. The drawings in this series are often annotated and labeled by the Atari design team.
