The Green Mystery of Onderdonk Avenue, Slightly Less Mysterious, And Perhaps More Sudsy

Two years ago, I blogged about this intriguing Ridgewood building at the corner of Onderdonk and Stockholm. I noted the odd color, the odd structure, and the presence, up top, of a number of Jewish stars and four-leaf clovers. I speculated that it was a religious building in the past, but find no evidence of such a past. At the time, there was garment work going on inside.

Recently, a reader wrote in, saying: "Green Mystery; Renovated our home (200 feet away). Found in ceiling on 2nd floor a green bottle with the Star of David. Could the building have been a brewery? Still have the bottle but can't make out all the initals; small b, large N over an A followed by Co."

Interesting. Anybody out there have a clue. I still can't find out anything about this building.

UPDATE: Commenter "Mingusal" sheds some light on the mystery below by reminded us of the six-pointed star's other symbolic past. Do we have a former German beer hall here?
