<VV> date this original Corvair dealership sign

[Carlton Smith]

Hi Guys,

I recently had a friend whose family owned a Chevrolet dealership in
Kentucky present me with the sign in the photo attached to this link
http://www.facebook.com/profile.php?id=1205061158&ref=name#/photo.php?pid=30
465408&id=1205061158.

The sign is made of formed plastics, it is apx. 24" x 12" and says "Corvair
By Chevrolet". Has anyone seen a sign like this before and is there someone
who can date it for me?

Thanks!
