We hear that a 17-foot-wide townhouse, where late NBC radio and TV producer Beryl Pfizer lived, at 349 E. 62nd St., is on the market for $3.85 million.

Just one month before her death at age 87 earlier this year, Pfizer ran the New Year’s Eve Midnight Run in Central Park.

Her 2,750-square-foot home, between First and Second avenues, comes with four bedrooms, three bathrooms, a fireplace, a balcony, a large rear yard — and buildable air rights.

The listing brokers are Leslie J. Garfield’s Francis O’Shea, Ravi Kantha and Matthew Lesser.
