Ah shame that no one bid here in the official auction.
I feel very sorry for the OP, as it quickly gives the impression that the work is not properly appreciated and there is no interest.
Unfortunately you don't see at the first view how much handwork goes into these timebanks - I think you really only realize that when you hold them in your hands yourself.
Still, a small success that they could probably be sold privately. I'm curious who can get hold of the last one.
