Can you identify this image?

This slide is one of a small group of World War I era glass slides depicting aviation activities that were found among a much larger collection of glass negatives and lantern slides in our old vault. As you can see, the slide is broken. Can you help us identify this image?

Thanks to a Special Collections friend, we have preliminary identification: WWI airplane appears to be a variation of the Vickers Biplane vintage about 1912-1913, certainly an early recon aircraft with a pusher engine.
