Sedgefield Jeans went all out for their promotion tied to the release of the
1976 King Kong. In addition to Sedgefield retailers giving away
keychains containing actual "hair"
from the Rambaldi Kong figure, they also sent out promotional folders to
retailers containing various promotional materials and suggestions for in-store
promotions, including a coloring contest for kids.
Scans of all of the pages included in the promo folder can be found below.
You can see photos of the keychain and a bunch of newspaper ads
here.
