The earliest currently known example of their use is from Moscow, Russia, where they were carried in a demonstration on 24 November 2012.[1] These flags were parted from bottom hoist to top fly, black field above the partition line and rainbow stripes, red at the top, beneath it. They were used jointly with the pink-black Anarcha-Queer flags, as well as the other Anarchist flags.[1] Another photo of such use was published in 2017,[2] but could have actually been taken at the same 2014 event, for it also displays one of the banners which were carried there.[1] Another photo of this joint use was taken in Russia by mid-2013, exact place and time not known.[3] The flags were used again in Moscow at the May Day demonstration in 2014.[4] The latest currently known example is from Warsaw, Poland, where the flag was seen in August 2018.[5] Tomislav Todorović, 15 May 2022 Sources:

Another variant of this design was used in Ankara, Turkey, in December 2015, again with the other Anarchist flags, pink-black Anarcha-Queer flags included. All these flags have had the width greater than the length, as is often the case with them in Turkey. In case of the black and rainbow flag, it was parted from bottom hoist to top fly, with the black field above the line again, but the rainbow stripes were arranged vertically now, red being placed next to the hoist.

The half black, half rainbow-colored Anarcha-Queer flag may also be parted from top hoist to bottom fly. Such flags were seen in Bristol, UK at the Bristol Pride 2022. [1,2] There, black field was above the rainbow stripes (red at the top) again. While the flagstaff of the photographed flag was not actually visible, the flag appearance (the way it was flying) made it possible to reveal the design details.
