Mystery RPPC: Century-old class photo

Here's an old real photo postcard featuring a school class photo from what was likely a one-room schoolhouse, in Somewhere U.S.A., some year. It's a Kruxo RPPC with no stamp box on the back. So I think that roughly puts it between 1910 and 1920. There's no writing on the back, and thus we know zilch about who these kids are.

It's always interesting to zoom in and examine the faces of all these children and wonder about how their lives unfolded. After doing that, this is a good place to start if you want to check out more RPPCs on Papergreat.
