What is the lineage of the Supercar emblems ?

[nuch_ss396]

I have long wondered about the lineage of the Supercar
logo's and/or emblems. Does anyone know where the crest
that Yenko, Harrell, Gibb all shared - came form?

Did Chevrolet license the crest to these dealers? Or, did the
dealers themselves collaborate on a design? Why didn't
Dana, Baldwin-Motion, and Berger use this same crest?

Was it collaboration between some and competition between
others?

BTW, this very site uses the same general crest design.
How did that come about?

I've often wondered about this but never bothered to ask
until now.
