Oxford Cross
A most unusual bowl, only a few reported so far. Some years ago, Glen and Stephen Thistlewood found one in Oxford, England--thus the name. They've been unable to identify the maker. Many thanks to Don Ruppel for sending me this photograph of his bowl. Note that the cross design is on the interior, the exterior has a star-type pattern.

Below are two views of a bowl that sold in 2020 for $55. I personally think it should have
gone for quite a bit more given the rarity of the pattern.
