I believe they're New York City public school children in the 1930s. The glossy photo is in good mounted condition. It appears to be cut from an old album.
Please see photos for details and size. Please note, I found a second photograph of this class.They're not too happy looking in this one either. I'll be adding it to this listing to keep them both together. See the last two photos for this additional image.
