The Morgan Library and Museum in Manhattan reopened this weekend after five months of renovations.
The McKim Building closed on June 1 to undergo a $4.5 million interior restoration -- the first ever at the Madison Avenue site.
Museum officials say with the new renovations, they will be able to display more artwork, music manuscripts, and books.
Items now on display include a mold of George Washington's face and some of Mozart's handwritten music.
"We've done absolutely everything. We've cleaned the marble walls, we've cleaned the marble mosaics, we've cleaned bronze doors, we've cleaned painted ceilings, we've installed wonderful new lighting throughout, it's spectacular. And then we've installed 300 of the greatest objects in our permanent collection to make those works permanently available to the public," said Morgan Library and Museum Director William Griswold.
"There's so much here, I mean how do you pick? And I think the things that they've chosen to highlight are really good," said one visitor.
The original building was once the private study and library of financier J.P. Morgan.
