A man who said he was a building superintendent signed for this huge $40,000 painting when it was delivered to a Tribeca building last month. The problem: The building doesn't have a super.

According to the NYPD, at 9:30 a.m. on May 15th, the painting, "Calming Freshness," a work by Harold Wong painted in 2000, was delivered to 321 Greenwich Street by Fed Ex. Police says it was "intercepted by a suspect who signed for the package. The suspect claimed to be the building's superintendent."

The painting was being returned to owner Bruce Brodsky, from Bonhams, the auction house that tried to sell it last year. When Brodsky didn't get the painting, the Post reports that he "quickly inquired with Bonhams, which launched a probe only to determine that a 'superintendent' named 'C. Hector' signed for the package at 9:30 a.m... Since there’s no super, Brodsky immediately knew something was amiss and called police."

Police describe the work as 48 3/4" inches X 120" inches wide. It's Ink and color on paper and inscribed and signed with six seals of the artist (depicted on the right side of the painting). The piece was described thus in a NY Times review of Wong's work: "As is often the case in tradition-based Chinese art, the painted landscape can evoke other organic things: microscopic cellular patterns, clusters of nerve endings, close-ups of skin. In a long horizontal piece titled 'Calming Freshness,' a mountain range is conceived as a series of near-abstract vertical curves suggesting a visual embodiment of sound waves."
