Also up at Phillips today was this nice little [25x25cm] seascape, Meer (Sea), a 1973 offset print by Gerhard Richter.
Richter replaced the sky in one snapshot with the sea from another. This particular example sounds like it had some condition problems, but with an edition size of 250, plus a dozen or more proofs, I’m sure a better one is never too far away.
