His classic ‘Mark’s Little Book of Kinder Eggs’ and book of plug wirings were always in print and I think the ‘Assume This Phone Is Tapped’ sticker was also one of his. There are phrases I’ll always associate with his work like ‘Aggressive School of Cultural Workers’, ‘Demolish Serious Culture’, ‘Book Shops Not Bombs’ and ‘N©’. He belonged to the anti-establishment DIY scene who used whatever they could to make art, was involved in The Exploding Cinema early on as well as the international mail art scene. It’s shocking to know he’s gone, a truly one of a kind figure. I’m sad I won’t bump into him at the fairs any more.
