I recently went to a garage sale and came across a vase/pottery. There was a gold sticker on the front that read Bay Keramik. On the bottom, were the words; West Germany, the numbers 534-25, all were molded on the vase. Then there was the number 28 stamped in gold in the center. At the top, it starts out gold colored, then blends into a cream, then into a chocolate brown at the base, and has a gold pinstripe ring around the bottom. I know that this company was started in the 1930's, and I would really like to know what it is worth. I paid $5.00 for it, and think it is a beautiful piece nontheless. I will try to find my camera so I can take some pics of it. Any help would be greatly appreciated. Thank you.
