Looking through the guy's other stuff on ebay is quite interesting.

This Roadbuster for example.. Makes me wonder about the designing of toys even more. Is that roadbuster a quick 3d model of the sort of thing they want in a deluxe sized toy? But even if it is, why go to the point of making a static figure first when some pictures would do the trick.

Or was this part of another type of toy that was due?

Oooo! The mystery

Wow, they even have some moulds on there too!
