NEW YORK (AFP) – Police in New York have asked for public assistance in tracking a half a dozen paintings by Andy Warhol and Roy Lichtenstein that were stolen from an apartment in November.

A police statement made public Friday said the burglary took place between November 24 and 28 when an unknown suspect broke through a hallway wall into the apartment and removed artwork, watches and other jewelry.

The painting include “Superman”, “The Truck” and “Camouflage” by Andy Warhol as well as Lichtenstein’s “Moonscape” and “Thinking Nude.”

“Live Cat,” a painting by British artist Carl Fudge, was also among the stolen objects.

Police have not revealed the name of the collection’s owner, but local media reports said it belonged to New York art collector Robert Romanoff.

The value of the stolen objects is estimated to be around 750,000 dollars.
