Lady Lovelylocks prototypes?

Does anyone here own, or has anyone here ever seen prototype dolls or outfits? I am very curious/collect prottoype/concept design stuff, and was thinking that I had never seen anything from the Lady Lovelylocks line.

I guess if there is nothing out there, we can just blame it on the fact that the fan quarter in the US just isn't large enough to motivate the designers to sell their stuff ...

but if someone has ever managed to collect something, I'd love to know about it/see !
