From one of the attendees:

"I attended the WOK auction yesterday on a hot and sunny Saturday in London. Saturday daytime auctions are never a good idea in my mind, especially in the summer when the weather is so nice. I also think it's a tactical mistake not to break up these long auctions (nearly 500 lots) into sessions so people can plan their participation a bit and not sacrifice all or most of the day monitoring the progress of the sale".
