Which leads to the follow-up question: Was "Graphic Information Services Inc." just a name for Al Capp's "shop"
producing work for commercial clients? Advertising clients and U.S. Government commissions were some of the most lucrative work you could get for comics. Both Will Eisner and the team of Neal Adams & Dick Giordano were famous for their commercial client work. While I was certainly aware of Al Capp's propensity for exploiting his characters as advertising spokesmodels, here the connection is distinctly subdued. Li'l Abner's appearance on the cover seems literally 'tacked-on', almost as an afterthought.
A good comparison for difference in approach to a U.S. Government-commissioned project is Harvey Comics' DAGWOOD SPLITS THE ATOM one-shot. Rather than just being utilized as a presenter or host, Dagwood, Blondie, and the rest of the Bumstead family take an active role as participants in the story, and Mandrake the Magician is heavily featured as well. Many other KFS characters like Popeye, Olive Oyl & Wimpy, the Katzenjammer Kids, Jiggs & Maggie, the Little King, etc. appear in more minor cameos.
