Follies of the Mad Men #76

[From The Saturday Evening Post for October 10 1953. Two scans, top and bottom.]

Nothing like aligning your product with a civilization that practiced human sacrifice. The Incas weren't the Aztecs, but as Wikipedia reminds us: "There is [sic] archaeological discoveries supporting the presence of sacrifice within Inca society according to Reinhard and Ceruti: 'Archaeological evidence found on distant mountain summits has established that the burial of offerings was a common practice among the Incas and that human sacrifice took place at several of the sites.The excellent preservation of the bodies and other material in the cold and dry environment of the high Andes provides revealing details about the rituals that were performed at these ceremonial complexes.'"

And did they actually make the best ink ever? I can't find any reference to such an accomplishment.
