I'm gonna make a guess about the poster
I know such graphics can be done super-laboriously by hand,
or very laboriously with Photoshop
But it can now be done by Dall-e 2
in 15 seconds (if you have access
to this new software)
DALL·E 2 is a new AI system that can create realistic images and
art from a description in natural language."Make a Rolling Stones SIXTY poster for Berlin Aug 3 with a
clear glass Stones tongue refracting a background image of
the Brandenburg Gate"
15 seconds later...
voila ! If I'm right, this poster will be an important historic collectible,
as the first commercial use of this new software (that will soon
destroy the livelihoods of many graphic artists)
And if I'm wrong... oh well, its still a nice poster.
