Contributed by Kenneth Greiner / Having recently relocated to London, I was delighted when a friend offered me a free ticket to the twentieth-anniversary Frieze Art Fair in Regent’s Park. On a sunny Saturday, I took the Jubilee Line tube from my new flat in northwest London to Baker Street before joining the line in front of the fair’s enormous white tent. This, I would discover, was where the contemporary works were on display. With 130 galleries participating, I knew I’d need to be a bit discerning if I was going to spend more than a few seconds with any particular painting. I soon found myself standing in front of The Only Thing Left Behind, a mid-size oil painting by British artist Martyn Cross at the Hales Gallery booth.
