Here's an ad for Oakwood Shopping Center from December 1960. (Click on it for a larger image.) Unfortunately the ad doesn't feature Oakwood Shopping Center's mascot, Oakie the Squirrel! (Click here if you don't know who Oakie the Squirrel is!)
The ad is very interesting though because the Santa Claus fiberglass statue promoted in the ad looks an awful lot like the one that Hot Dog Heaven displays in front of their restaurant in Amherst (at right). In both poses, Santa is writing in his book. They may be painted a little different (the white fur trim above the boots, for example) but at the very least they look like the same mold might have been used for both.
