“Lancaster Sandland Hand painted Hanley England”. The inscription was as enigmatic as the design. I held the mug in my hand wondering what the two figures on it meant. You’ll be my first customer today if you buy it, the woman in charge of the stall said. It had just gone two o’ clock on a sun-draped, summer afternoon. I offered her a couple of quid and she took them. I think she’d have even taken 50p for the item.
