Hello!
Just wondering: how much value is added to a set when it is signed by the original
designer(s)?
Thanks! 😊
It's difficult to say, there are people who collect this kind of thing, but
the market is too small for anyone to have reliable (statistical) pointers. In
similar questions here in the forum, I've seen suggestions to sell it via
an auction site, that's probably a safer way than hoping to find the one
person who'll pay a boatload of money for it on Bricklink...
