Przemysler's Ball

My laptop crashed last week and while transferring over data to the new one, I came across a wonderful old photo someone sent to me several years back. (Who? If this is yours, please email me!)

The inscription reads: "Przemyslers ? ? ? Arrangement comm(ittee) of the Ball Dec 16, 1911.

I assume this was a big annual soirée of Przemysl immigrant (youth?) in New York City but I've not been able to find anything concrete. Anyone know?
