An example of American marketing well before the Mad Men era.
In 1939, Ronald S. Renaudin (1912-2001), the manager of Gulf's Central Service Station on Canal and South Claiborne Streets sent this ad to Guy Seghers Sr. (1898-1986), a local surveyor. Seghers, bless his heart, was a very thrifty businessman who saved every scrap of paper that came his way -- calendars, advertisements, envelopes -- in order to sketch out his lot surveys and transcribe chain of title information on the blank back sides. In this case, the verso of the advertisement delineates street lines associated with a property in Square 627 of the First Municipal District of Orleans Parish.
Gulf's 1939 personalized direct mail advertisement featured an illustration by John August Groth (1908-1988), Esquire Magazine's first art editor, most widely known as a teacher at the Art Students League and for his illustrations of American military combat. Some of his depression-era social commentary drypoints may be viewed at the Smithsonian American Art Museum's website here.
