Ilon Gallery featured in New York Post

While most art galleries are located in spacious studio and loft spaces, Efron runs Ilon Art Gallery out of the late 19th-century brownstone she shares with her family at 204 W. 123rd St. in Harlem.

Efron has run a successful photo archiving business, Ilon & Company, for two decades — working with the likes of David LaChapelle and Annie Leibovitz — but in 2014 she expanded her business to include a gallery in her 4,500-square-foot townhouse that’s open to the public.

“I had been collecting pieces for 20 years, hanging them on my walls, and they looked amazing,” says Efron, who also recently launched iArchive, a database management tool for photographers.

“So I decided, ‘Let’s do a show. Let’s make it a real gallery.’ ”

Fast forward two years and several installations later, and Efron’s current exhibition is “Music.”

Running until June 3, it features more than 70 snaps of iconic musicians shot by celebrity photographers.

They hang on walls throughout her four-story home.

The majority of the photos on view are in the parlor floor’s main room, which features soaring 11-foot-high ceilings. Highlights include David Bowie by Claude Gassian, Lady Gaga by Martin Schoeller and Keith Richards by Gered Mankowitz.
