What is this tyke sitting on, what’s he doing and what businesses are standing where these building are now? Bonus if you can guess the date this photo was taken.

Last week’s Thanksgiving Throwback Thursday photo courtesy of Maine Historical Society/Maine Todaywas taken at the Chestnut Street School in Portland, circa 1924.

The provider of this week’s photo will be revealed next week so we don’t give it away!
