There is an interesting aucion going on Ebay this week. Lots and lots of wonderful classic images up for sale by Edward Weston, Ansel Adams, Imogene Cunningham, Tina Modotti, Newton, Irving Penn, and so many others.
Here is the link to the site. http://search.ebay.com/_W0QQsassZphillipsdepuryQQhtZ-1
If you have an extra few thousand dollars? Bid to your hearts content. But check out one of Tina's images! The starting price is $130,000. Gosh, I hope that's a type-o.
