From a private collection in Cambridgeshire, whose owner described it as "charming, if slightly knarled." Carved, not turned, and appealingly out of true (ie wonky). Most 16th-century tablewares of the middling folks were made of wood, but very few have come down to us today. Here's one of them. Don't you like the early appearance of the round bowl and square foot? Sycamore was often used for drinking vessels because it did not taint the drink.
