An exhibit showcasing items buried in the Egyptian tomb of King Tut is back in the United States.

"Tutankhamun and the Golden Age of the Pharaohs" has opened at the Dallas Museum of Art, the first of three museums to host the encore tour. The other two host cities have yet to be named. At least 1 million visitors are expected in Dallas.

"We look at this as a once-in-a-generation opportunity," said Bonnie Pitman, director of the Dallas Museum of Art.

The exhibit, in Dallas through May 17, features four artifacts that are part of the last tour, including a necklace, a bracelet and two nested miniature coffins that contained a mummified female fetus. The fetus is not part of the exhibit, but a photograph shows the mummy in the coffin. DNA testing is being done in Egypt to determine whether that fetus and another fetus found in the tomb are Tut's offspring.

About 4 million people visited the exhibit as it toured four U.S. cities from 2005 to 2007.
