Burma-Shave (1930)
Another lost piece of roadside Americana, the Burma-Shave advertisements were placed one line at a time on small board road signs along country highways, with a spacing of maybe 200 yards and the last sign was always Burma Shave. At the height of the campaign, there were 7000 of these on the roads. See http://www.quiltbus.com/burma.htm , and also here, for the story.
