How far back do you want to take this? Like why aren't they giving credit to the person who invented the pen? C'mon, this is a much more direct copy of Monument Valley than Escher.
Monument Valley is a copy of Escher so I’m not sure your point. Or maybe it’s an order thing? Then Monument Valley is a copy of the Escher scenes from the movie Labyrinth or maybe it’s a copy of a-ha’s Take me on music video?
