Very cool interview with Alexander Zacke: "People are coming from all over the world to these auctions. They will register and then 30 minutes later, buy a piece for $100,000 and send the money the following morning." Wow.

The interview is quite insightful – in particular, how this team failed once big time, before managing to crack this market.  A market that Ebay (and others) unsuccessfully tried to develop.
