While digging through the vintage ads we have digitally scanned, I came across an article talking about an "Attex No. 1 for Family Fun" commercial. The article was published in June 1971. Here's what information is provided:

-John Burford of B & H Sales in Marietta, GA.
-Around the time of the 1971 Chattahoochee River Race.



I bet it's out there in some archives!
