Height: 10 1/4"
Color: tan with beige dimples and blended chocolate up one side
Condition: no cracks or recent chips. There is a 3/8" flake off the blob that looks ancient, possibly from manufacturing. There is also a small potstone in the glaze with an unglazed pockmark, which is defintiely manufacturing and shows the crudity.
