Illustrator and comic creator Tomer Hanuka has produced typically stunning cover art for all of the 7" singles released for Jack White's debut solo LP Blunderbuss. They are alternates available only at venues hosting White's current tour (or subsequently on eBay, reality fans). Placed together, they form a tetraptych.
Four panels, split by time, alluding at a narrative. Does that make this one of the hardest-to-obtain comics of all time, then?
