Unfortunately, that is not the case. I wish it was true though.
The artist whose art has been shared by Guy on his IG acc said on Twitter that she hasn't been contacted by the band in any way (yet?).
This is literally what she said on Twitter:
''Oh my God lmaooooo As of right now: they haven’t contacted me for art or licensed anything!! I think he just liked the piece and wanted to post it! ''
Here's a screenshot I made from Twitter:
This feels like a direct reference to it... Guy has been sharing a bunch of surreal artwork from different artists lately. Maybe he just loves surrealism... or he's just sharing some art from the people the band has been working with lately! :O
