On May 23, 1938, Narberth Public School presented a Historical Pageant in Narbrook Park with scenes from Indians and early settlers through World War I. Here boys dress up in Union and Confederate uniforms for the episode "Preserving a Nation", depicting the Battle of Gettysburg. The 75th Anniversary of the battle that summer was the last to host veterans of the Civil War.
The location of the photo is the Narberth School playground, now divided between a parking lot and Sabine Park.
