They're accepting any Revell kit, Revell of Germany kit, "Revelllogram" kit (but NOT "pre-merger Monogram kit reissued in a Revell box" kits!), for the special theme award.
I am also reminded of a long ago conversation with Mike Siegman, who was the President of the Metroplex Car Modelers Association back then (late '80s/early '90s). I told him when I joined the MCMA that one of my first model cars was the 'Ye Olde" '56 Chevy, and he replied, "Gee...and you STILL build model cars?!?"
Revell '57 Ford and the first-gen Bronco are the most recent Revell builds I've done...and I did more than one of each!!
