Greenpoint's Manhattan Furrier In Peril?

I've posted in the past about Manhattan Furrier—which is not in Manhattan, but on Manhattan Avenue in Greenpoint, Brooklyn. It's a curiosity that was founded in 1913 by the father of Irving Feller, who (I assume) runs it today. Feller, 81, is the sort of eccentric you'd only find in New York. He is an abstract painter in this spare time and his works fill the walls of the small place. He is also obsessed with Native American culture. He has visited the Kutenai, Shoshone-Bannock, Crow, Nez Perce, Apache, Navajo, Zuni and Hopi out west. In his store window are Native American jewelry he has bought from them; everything is for sale. Manhattan Furrier also offers fur storage, of course.

Today, a Greenpoint reader wrote it, worried, saying that Manhattan Furrier has not been open for months and there is a "for sale" sign on the building. One day recently, the reader noticed the metal gate was up and quickly took a few photos, seen below. It appears the store remains as it always was.  Does anyone know what's going with Feller and this store?
