Steve, your inner Cliff Clavin is only due to the fact that it was your car featured in that article. :-)
In case some of yuz don't remember, I'm working on a book:

I've taken a few pics of the catalog from Tony D'Agostino's collection (hence the sideways photo I uploaded), and I currently have borrowed someone else's dealer merchandising book, but I haven't glanced through either to see if the tickler is there.
In the link above, I occasionally post some of the more unusual items I've found in my research, including some Mopar advertising items. Right now, I'm trying to reconcile the premise that Chrysler usually wasn't the first with the crazier items from the muscle car era, but when they adopted them, they ran with it.
