And you know what? They spent the whole conversation talking about Gossip Girl. Well, they would've done—had the super-rare, never-seen-before footage not been filmed in 1922.
British Pathé dug up the footage, and is on the look-out for anyone who might have some information about who the women are (or were), or those who might know about the (mobile) phone used in the film.
The video below shows the women using an umbrella as the aerial, with one of them wrapping the phone's wire around the knob of a fire hydrant. Then, they hear sweet 1920s twinkly music played down the phone from the telephone operator's gramophone.
One of the subtitles to the silent film says that it's "Eve's portable wireless phone - and won't hubby have a time when he has to carry one!"
Despite the film's age, it would be many decades later until Eve's "hubby" was able to carry around the world's first commercial (mobile) phone—the Motorola DynaTAC 8000x, in 1983. [The Telegraph via Recombu]
