From our background knowlege, we know that for the game of horseshoes, you need sticks to throw a little ring around them. This game could help the children with their aim. When the boys grow up, they need good aim to shoot and kill wild animals for food and blood. That is what we think this Mystery Photo is. Its a board game.
Kids use the stones as markers and move around the board.
In other words, a clever little device used when they want to pick someone randomly by spinning the stick in the middle. Its a building toy, like our LEGO blocks today. Maybe you have to throw the stone into the circle formed by the sticks. Like our darts game or our basketball game. Or maybe a device to practive accuracy when hunting, pretend the board is an animal.
