The Munich Horde

Painting by Marc Chagall
This is but one of the pieces taken from the horde of looted art found in the home of Cornelius Gurlitt. It's a previously unknown painting by Marc Chagall.

You could argue that this work was saved or preserved but, really, it was stolen and hidden by someone with a dangerous mindset. For decades to come, we will see similar finds. We might never again see 1,500 works appear, almost instantly, in an avalanche, but we might see something of the tens of thousands of pieces that are still missing.
