As a crazy, loopy definitives collector I have long been intrigued by the Machins. Large collections in Vario pages are an incredible sight to see. Alas, I have been too intimidated to take the plunge but perhaps sometime in the future.
But with a graphic like that, many might be attracted into taking the dive! That is an amazing composition, really. Can you say where you found it? Sort of a wall poster? I don't collect Machins, but that is a stunner.
