One of the two Nicholas Roerich works stolen in June and reported by Art Loss Register were returned to New York’s Roerich Museum by mail, according to the Associated Press:

The director of the Nicholas Roerich (ROE-rich) Museum says the painting, “Talung Monastery,” will be examined Monday by detectives looking into the thefts. It was sent back in a manilla envelope between two pieces of cardboard. Director Daniel Entin says it had a return address. He won’t say who sent it because the investigation is ongoing. The other stolen artwork was a pencil sketch, titled “The Himalayas.” It was stolen June 24. The returned work was discovered missing about four days later.
