I guess I was not alone in following this incredible auction - incredible in terms of results that is.
I could not believe my eyes and ears as a Mark Hamill signed 8" x 10", nicely dedicated to Prowse, went for £15,000 (nearly £20,000 including fees etc.) and similar Carrie Fisher for £11,000 before fees.
In some ways I was even more amazed at what some undedicated lots on repro or fan convention items fetched (Hamill up to £4,700 before fees, Fisher £3,600 before fees). I have no idea what the more minor characters usually fetch but there seemed to be some incredible prices there too. I do know that Dave Prowse's own autograph wouldn't normally fetch up to £1,600 before fees!
Going off topic, most of the non-autographed items went for well over normal market prices too.
I know star association carries a premium but if the object bears no evidence of having being owned by the star I'm not sure that much of a premium is really justified. Mr. Prowse was also not exactly in a leading role either - face never seen, voice never heard as far as I know.
Here is a link to press report and a link to the results.

I know that the auction did benefit a charity to an undisclosed extent. Maybe some bidders were bidding so high to donate.
