A 1941 photo of children queuing outside a Chicago cinema has gone viral on Reddit, after users spotted a boy near the back apparently holding what looks like a tablet. Naturally, some have decided this is proof of time travel.

The photo in question

Taken by photographer Edwin Rosskam, the image shows a line of smartly dressed children waiting to buy tickets, a scene that would have been completely unremarkable at the time. One boy on the far right appears to be gripping a flat, dark object, and that's all it took for the internet to run with it.

The obvious problem: the first iPad wasn't released until 2010, 69 years later. Reddit users have had a field day with the theory anyway, with one declaring the photo "proof of time travel" outright. More grounded commenters have pointed out the far likelier explanation — kids in their Sunday best, heading to the cinema, were far more likely to be holding a Bible or a hymn book than a piece of Apple hardware from the next century.

This isn't the first "time traveler" photo to go viral

Photos and footage seemingly showing anachronistic technology have been a recurring source of internet fascination for over a decade, and this Chicago image fits a well-worn pattern. The most famous example remains a 2010 viral clip from the 1928 Hollywood premiere of Charlie Chaplin's The Circus, in which a woman can be seen walking past holding an object to her ear, apparently talking into it.

Filmmaker George Clarke, who first spotted the clip, argued at the time that she appeared to be using a cell phone decades before they existed, and suggested she might be a time traveler. The clip drew over a million views and made international news.

Researchers later offered a much simpler explanation: portable hearing aids, sometimes called "ear trumpets," were already being manufactured by companies like Siemens as early as 1924, and were compact enough to be held to the ear in a way that, from a distance, looks remarkably like a phone call.

Why our brains keep doing this

Cases like these tend to follow the same pattern. A blurry, low-resolution detail from old footage or a photo gets reinterpreted through a thoroughly modern lens, and because our brains are wired to spot familiar shapes, an ear trumpet becomes a phone, and a book becomes a tablet. It's less a case of impossible technology showing up in the past, and more a case of people looking for patterns they already know, and finding them in objects that never had any connection to the future.

Whether it's a Bible, a hearing aid, or something else entirely, the mystery box in the Chicago photo is almost certainly not an iPad. But given how much fun people are clearly having with the idea, don't expect that to stop anyone any time soon.
