Selling the $73.8 million triplex penthouse at office-building-turned-luxury-condo 212 Fifth Ave. might take some time.

So, to boost its profile, James Cavello — president and co-owner of Westwood Gallery NYC — is installing an art collection with work from Andy Warhol, Douglas Kirkland and more.

The setup debuts on Jan. 24.

The 10,079-square-foot home comes with five bedrooms, a marble foyer, a private elevator and a library.

Its terrace measures 4,700 square feet, which is enough room for your own pool.

The listing brokers are Brad Ingalls, Mara Flash Blum, Nikki Field and Kevin Brown of Sotheby’s International Realty.
