This week, I was visited by a cousin from Pittsburgh, who brought me a copy of Klaus Honnef's little book on Warhol.  This came with a very tempting offer to put me up while I visit the collections at the The Andy Warhol Museum.

Warhol is part of the fabric of the city of Pittsburgh - my cousin gets her rubbish collected by Warhola Recycling.   Still, it was a happy coincidence that she brought me that book a decade or so after his photobooth works showed in a retrospective at the National Gallery of Modern Art .
