There was a time when BF Goodrich didn't just make tires. They also made sneakers for kids!
The PF Flyers came from Goodrich, and were pretty big in the 60's, but less so as I was growing up. I don't recall ever owning a pair of PF Flyers. Ever. Enough digression.
Anyway, BF Goodrich contracted Hanna-Barbera to use Jonny Quest for advertising to promote the sneakers. Scope it.
