The most known images of time travelers from throughout history

This image from 1943 shows British factory workers escaping to the seaside for a break during the midst of wartime. The clothes and beachwear of most people certainly fit the era, but in the center of a frame appears to be a man dressed like Mr. Bean checking his mobile phone. Or maybe it's a time travel device? Likely a bit of a stretch or a case of overactive internet imagination, but we still enjoy the thought. Maybe there are no public beaches in the future?
