Photo Number 502

This is a group photo that I purchased at a Antique Store in Dorset, Minnesota. There are three stores..I got this one at the second store. 

I will let you tell me what you think the story behind this photo is..and if you think like I do that those four boys were a bit much for that Grandma.  What year do you think this was? 

Jno. P Trlica was the studio in Granger, Texas.

Thanks for stopping by, do come again:)
