So they're not real.....sigh.....Oh well, they do look cool!!! Near as I can figure it the Airstream looks kinda like a 1954 Wanderer and the Cadillac is a 1947.
The number belongs to Don & Joan Weaver of Birdsboro, PA. I don't know if they know that their number is famous! I don't think the Chinese really care one way or the other, since the nameplate says "Camper", instead of "Airstream". I'd like to see Jackson Center sue China over copyright infringement on this....that'd be a hoot!
