Glass Slide Negatives
This is a "colorized" image of what looks like a group of kids having just played some sort of ball game. You can see the somewhat deflated ball in the foreground but I'm not sure if it's a football or basketball. I used a freely available web service to colorize the original black and white image.
Guessing this is a group of engineers. It's a wild guess but there are bridge structures just like this in downtown Brockton under the MBTA railroad tracks.
Looks like a photography club out capturing landscapes. You can't see it in this photo but when I zoom into the dark square sign on the tree, there are two advertisements. One is for the Besse Baker's Department Store and the other is for the L. E. Higgins and Company who had a store in Taunton.
Another guess but this looks like a photographers club outing. Note several bottles of Moxie Nerve Food on the table. On another bottle, you can see the partial label with Bob's Coffee showing.
