While watching a video of deployment of Soyuz spacecraft, I noticed a flag next to the launchpad, with sign 'Baikonur' and a graphic of Earth and several stars; one I didn't see anywhere else:
Every search for 'Baikonur flag', in English and Russian, return either the standard: ,
the flag of Kazakhstan:
Baikonur badge/logo,
or assortment of commemorative badges and independent designs by people without any association with Baikonur or Roscosmos. I managed to locate what seems like a very old print of an old variant of the design (with a simple globe of meridians and parallels instead of a picture of Earth) on the flag on a Flags of the world site:
and a photo of a flag with this version:
...but nothing closely resembling the one from the video.
When was that version introduced, what is its relation to all the others, status (an official symbol or just a decorative variant?), and does anyone have a better image of it?
