I took a look at the items in question, and the "low" bid price is way too generous! One can find comparable examples on eBay with regularity at a much more reasonable "set-back."
Re: March 2010 auction of Charlie Chan photos (OOPS!)
Dear GWS,
I just took a second look, and I realized that the auction lot consists of 54 stills. At first glance, it seemed to me that there were only the four pictured images on auction. At the minimum bid estimate, that would be a good deal. However, it seems that there is a "vintage stills and later strikes." This is less good.
