Can you identify this?

Our Special Collections Department is processing thousands of negatives it received from the North Adams Transcript. Many of those negatives have minimal, if any, identification, so from time to time we will post an image here and ask you to help identify the people, place or timeframe. Please help us out!

Here's the first. The envelope was labelled "Churches", and it appears that there is a nun in the center of the photo. Perhaps someone can identify at least one of these people, or even the room. The photo probably was taken sometime in the 1930s - 1950s(?)
