A thief posing as a patron stole the dedication plaque from the Waldorf-Astoria’s national landmark World Fair Clock the day before the hotel closed to the public, police say.

Video shows the crook exiting the hotel with two women at around 1 a.m. on Feb. 28th, the very last day the hotel was still open before a major renovation project was to begin.

Cops say the man was seen hanging out at one of the hotel’s bars earlier that evening with the women, whose relationship to the thief is yet known.

The World Fair Clock, crafted in 1893 and sold to the famous New York hotel in 1931, is the centerpiece of the national landmark lobby.

Cops say that the plaque is valued at $100.

The man is described as a white male and was last seen wearing a white dress shirt with a dark tie, dress pants and a dark jacket.
