Where did the founder of Chevorlet find the bowtie that is now world known?

on the wallpaper of a hotel

...in France.

... and although some stories indicate that William Durant found the emblem in 1914 on some wallpaper in a Paris hotel room ... .... others say he actually tore off a piece of the wallpaper with the design from the Paris hotel room in 1908, and kept it in his wallet until he found a suitable use for the logo ... ... and it was first used in 1913 on the Chevrolet Royal Mail and Baby Grand models ...

Yeah. the wall paper was in the bathroom
