This General Motors Harrison Air Conditioned sticker appeared in almost all GM cars thru the 70's
possibly as early as the late 1960's.
If the A/C unit was under the hood on the passenger side of the car this Harrison sticker was located in easy viewing.
Approximately 2 1/2 inches by 1 inch, it has our patented "Peel and stick" format but with the adhesive on the back instead of our customary adhesive on front.
