I did a cartoon treatment of the Big Eight CPA firms around 1980. For some reason Peat Marwick (later Peat Marwick KPMG) had the Pep Wheat Flakes guy. Free association.
I was thinking of the Pete’s Bicycle Shop guy in New Haven, who never failed to advertise in every and any Yale student publication, 1930-1980. “Everybody Knows Pete!”
This had nothing to do with financial accounting, but they loved it at Touche Ross. Peat Marwick had ESSO/Exxon, while Touche had to settle for Associated Dry Goods and Chrysler.
