For your consideration is this large and unusual studio pottery bowl. It measures 11 1/2" tall and 17" in diameter.
There are markings on the bottom, but I can't say for sure if any of them are actually a signature. Also, there are many, many folds and rough edges incorporated into the decoration, but the only thing that appears imperfect is what looks like a burst bubble shown in photo 11. Never seen anything quite like this one. Please study the photos and ask any questions you may have.
