Saw someone with this pfp on here and it reminded me:

It's the symbol of the communists in the fictional world of the videogame "Disco Elysium."

The creator of the game is from Estonia and thus their perspective of communism comes from their local history. The game is a little doomer-pilled about communism but overall I'd say their political takes and implications, while plenty self-deprecating, pessimistic and snide, are usually very solid.

Copy and pasted from the wiki:

The symbol was created 40 years before the current century, eventually being adopted by Mazov and the communards. The wreath of antlers represented a society that could both exist alongside and rule over the natural world, while the five-pointed star, a social-democratic symbol, was turned upside down to symbolize the toppling of the old order. The colour white was chosen as it is the colour of peace, also seeming to complement the black used by anarchists.
