Hi gang

Back in a previous life (possibly referenced in those links given at the head of this string which I cannot get to open) some discussion had taken place on the history of Tom Swifties. I understand the general background of a piss-take of the adverbially overladen books by the Stratemeyer conglomerate… but I had recalled my American brethren and sistren talking of a major advertising campaign (an oil company, in the 50s?) which widely popularised the form as roadside billboards.

Google has failed to cut me a path through the jungle – any pointers?
