(Getty Images) (Newser) – Looking to invest in a piece of the New York real estate market? Well, soon you may be able to invest in the biggest piece of all: the Empire State Building. The Malkin family, which controls the building, is trying to create a publicly-traded real estate company that would feature the landmark as its headline property, the New York Times reports.

If they do manage to come to market, they’ll be cashing in on the significant work they’ve done to renovate the building—like restoring its Art Deco lobby murals and improving its energy efficiency. “They’ve moved the building, in my mind to a Class A property,” said one real estate exec.
