Rabbis DOLGINOS and JERUSALEMSKY,New York City early 1900s. #usa #rabbinic

Yonatan Ben-Ari

I have  picture of a hebrew class in, i presume, N.Y.C. early 1900s, which on the back is scribbled Dolginos and my father-in-is sitting in the middle, presumably as the teacher.  Besides this picture i had no idea of any connection between the 2 rabbis.
 Does anyone know someone who was a student in Rabbi Dolginos' synagogue (or school) and could identify the persons,time and place of the picture.
