"I killed Einstein, gentlemen," or a 1960s self-stick hybrid with a polaroid

The user reddit ZaHuBa discovered and brought to the public a scene from the 1969 science fiction comedy (according to iMDB - 1970) called "I killed Einstein, gentlemen." In the scene, the characters use a device that is extremely similar to a selfie stick, which also can produce ready-made photos.
The fantastic comedy "Zabil Jsem Einsteina, Panove" produced by the now defunct Czechoslovakia tells how in the near future the explosion of a nuclear bomb led to the fact that women lost the ability to bear children, but acquired the ability to grow a beard.
The United Nations Consultative Council decided to build a time machine, go into it in the past and kill Einstein, because without his calculations, according to the voters, it would be impossible to make an atomic bomb.

The device is a telescopic stick, similar to modern selfie sticks. Apparently, a tiny camera with a flash is built into the thin end of the device, while the thick one is capable of instantly printing finished photos on paper.
Users even found a link to the full movie on YouTube, but unfortunately the video has already been deleted.
