Zazzle. I've had a number of items up on the site for a couple of years, but having not expended any energy in promoting them, I've had no sales (not unsurprisingly).
I think this is one of my favourite photographs from my visits to the Bay of Naples. It's a tiny fresco in the Villa Oplontis, and it's been painted so delicately that it's remarkably life-like. It makes such a different statement from the other, gaudier rooms in the Villa.
