I once had a Sunday comic, cut from a newspaper and pinned over my desk, that had John Hartford playing a banjo with a riverboat in the background. A speech bubble over John's head said, "'A banjo will get you through times of no money, but money won't get you through times of no banjo." I've lost it.
I believe the comic strip was called Gasoline Alley. I can't find it on google images, but I'd love to find it again. Does anyone have any ideas...or does anyone else remember this comic?
