There’s always something daunting about huge international art fairs. However, what struck me about the rich mix of work on offer at the London Art Fair was something sensory and almost visceral. The turpentine tang of newly finished works in oil by young artists mingled with the curiously musty aroma of lithographs, linocuts, etchings and prints by 20th century masters like Piper or Hockney. The Private View at the Business Design Centre was teeming with artists and buyers and, judging from the deals I overheard on stands, the appetite for art, old and new, is as intense as ever.
