RD 119® The Miracle in Your Gas Tank

Published in 1950 by Sinclair Research Laboratories, Inc., this single-issue comic served as a promotional piece blending educational content with corporate messaging. It aimed to explain the science behind Sinclair's RD 119® gasoline additive in an accessible, illustrated format for a general audience. While not a traditional narrative series, it stands as a curious artifact of mid-century industrial advertising, reflecting how companies once used comics to engage consumers with technical product claims.
