The old WGBH/ 2 logo (Aztec pictograph)

Remember it? A pictograph representing a man, a woman, and their children...a family. As seen on bumper
stickers for years.

When I was a kid, I thought that symbol was the face of an evil owl! "Learn or DIE!"

Ah! indeed.

To me, this: http://www.retrojunk.com/details_commercial/1343/ has always been the WGBH symbol (sometimes with a 2, instead of WGBH written out).
