I am happy I did not miss the deadline for my entry cause this round has amazing prompt. I see a lot of nice entries already were provided, among them I was impressed most with @apnigrich find. These copper DIY-stampings from the soviet epoch look like a champion entry for me! But anyway, even with no hope for the win, I enter - with this piece of art I stumbled upon today:

Yeah, its very same retro-nostagia for the soviet epoch.
(By the way - I found it at a kids playground in the neighboring yard). If you like it, do give your vote to support my entry in the contest. My best wishes to other contestants, and those who curate / support the participants.
