Tam and I were in the office; I had just located a photo of the Wizard Oil Bridge and was telling her that, despite the web-page report that "...no one has ever been able to tell me it's name origin," artist/historian Eric Sloane* wrote that the current bridge is named after a patent medicine advertisement painted all across the outside of the covered bridge it replaced: WIZARD OIL.
Tam, faux-impressed: "Do you know how many wizards you'd have to press...?"
She should know. Oh, my. --Back on this earth, Hamlin's Wizard Oil didn't just paint signs on bridges, they promoted their nostrum with medicine shows and printed songbooks.
* Eric Sloane's America, pp. 87-88. (Promotory Press, 1994, reprinting Barns and Covered Bridges , Our Vanishing Landscape  and American Yesterday ). --If you see a book with his name on the cover, buy it if you're at all interested in hands-on history.
