Police last night recovered the 2,500-year-old Greek marble head, worth an estimated $150,000 that was stolen from the Metropolitan Museum of Art last Friday during normal visiting hours.

Police said the untitled work, depicting a bearded man with wavy hair, was found in good condition in a baggage locker at Grand Central Station, about two miles from the Met.

The statue was found after National Broadcasting Company security guards told police they had received an anonymous call. They told police the caller specified the locker number at Grand Central.

Officers went to the station about 9 p.m. opened the locker and found the marble head. Museum officials who later viewed it "authenticated" it as the missing statue, police said.

The robbery was described by the Met, which spends about $3 million a year on security, as the first major theft in the 110-year history of the museum.

The fifth century B. C. head, almost life size and with a slightly damaged nose, was wrenched from its wooden pedestal when the gallery in which it stood was left unguarded for 10 minutes on Friday afternoon.

The Met said the 20-pound head, known as a herm, had been seen in its usual place by a guard just before he was scheduled to be replaced.No guard patrolled the area during the period in which the head was believed to have been taken.

The statue was one of four such marble heads in the Cypriot gallery. It was bought by the Met from a private collector in 1959 for $15,000.

At the time the theft was discovered, the museum said the FBI had joined the New York City Police Department in the investigation.

The Met, which has more than 300 galleries, had recently stepped up anti-theft measures because of the King Tut exhibit which will be at the museum until April. CAPTION: Picture, The recovered Greek marble head
