Not Seen This One Before!

[Super]

I don't think I have seen this Vintage Plarail/Tomy release before. Since it has the vintage Boy & Girl Logo it had to appear between 1967 & 1981. Not sure exactly what it is called but there looks to be two versions, one with a white roof and one with a gray as this seller shows. What I find interesting is that its not a friction drive but axle driven. Might this have been a very limited release?
