I seem to recall that it was something from Revell, but I've checked both the Club de Mer and the '57 Ford woody wagon, and zip.
The Caddy kit from the period had a standing girl in a formal gown, so that's not it either.
Hmmmm...I also don't think it was the smaller scale Chris Craft boat, and photos would seem to back that up...though there is a reclining one that I might remember incorrectly as being larger and standing.
Any insight appreciated.
