In the 1969 sci-fi comedy Zabil jsem Einsteina, pánové… (I Killed Einstein, Gentlemen…) from acclaimed Czech director Oldřich Lipský, a man travels back in time to kill Albert Einstein after a nuclear blast results in women growing beards and losing the ability to have children.
In an early sequence in the movie set in the year 1999, a character played by actress Iva Janžurová wants to take a quick photo with her soon-to-be time-travelling husband.
She pulls out a device that looks strikingly similar to the modern selfie stick, poses for a shot, and takes a snap. The stick immediately prints out a photograph, which the Janžurová character gives to her husband as a memento.
A GIF from the movie depicting the device made its way to social media today through the Facebook page of FFabula (a student union at Charles University):
And the entire movie is currently available on YouTube. Check out from about 9:20 for the clip in question:
Zabil jsem Einsteina, pánové… is also available on local DVD (albeit without English subtitles) and highly recommended.
