KING GNU's 2023 release "THE GREATEST UNKNOWN" poster, - Title: THE GREATEST UNKNOWN - Artist: KING GNU - Release Year: 2023 Thank you for viewing. This is a King Gnu poster. It was too big to photograph well, unfortunately. However, I haven't displayed it, so it's in good condition without any sun damage or pin marks. I'll refrain from listing it as "new" since it's been stored by a private individual. I look forward to your purchase.
