Incolay Studios of California Bell in Incolay Blue -- Excellent Vintage Condition.If you collect bells, this may be a fined addition. Marked INCOLAY in raised block letters on the interior rim, this piece seems unusual to me. It has a bisque feel to it and features old sailing scenes similar those seen on Delft pieces without the windmills.It is 7 inches tall and 3.5 inches in diameter and has a pleasant tinkle sound when rung.
