Organizers also say 19 new artifacts from the boy-king's tomb were added this week. They include a miniature bronze dog and sphinx-shaped bracelet ornament. They say the Discovery Times Square Exposition show will now close Jan. 17, 2011.
The additional items come from the Metropolitan Museum of Art. Last month, the Met and Egypt's antiquities authority said the objects will be returned to Egypt and become part of the permanent King Tutankhamun collection at the Grand Egyptian Museum slated to open in 2012.
New York's exhibition opened in April. It sheds new information about the life and death of Tutankhamun and his ancestors, based on discoveries made through DNA and CT scans.
