Christie’sThere is a slightly unusual oil-on-photo. Estimate is GBP 25,000 – 35,000.

GERHARD RICHTER, Untitled, 2003
signed and dated '6. März 03 Richter' (on the mount); signed and dated again '6. März 03 Richter' (on the reverse)
oil on photograph, 14.6 x 10cm.)

White and green oil paintings on a vertical photo of the sky. This is a rare type. When you enlarge it, the oil is on it quite well, and it's not bad for people who like this color. It seems to be a work sold directly by an artist to someone close to him.

 

Postscript: As a result, it was sold at a ridiculously high price (113,400GBP = 18.54 million yen). I think it's one of the top three oil-on-photo prices in history.
