This is a beautiful piece of studio art pottery and I have looked at this signature about a thousand times and I can't make it out. Maybe Don Pottery? Maybe Don Pot???. My lack of knowledge is probably going to be your gain. In excellent, clean condition, this tall vase with lid is part sculpture - the top has an attached finial of ironwood or similar dark wood figures that appear to be a couple standing on top of two pottery beads and a crescent moon that's also made of wood, with wire embellishments all around. I would recommend anchoring the base with putty that's made for such things, because it is quite a small foot for such a tall piece. Speaking of tall, it measures just under 22" to the top. What a statement piece!
