Antique Stoneware Mautz Brand Marked Ball Lock Cheese Crock. Rare find...I can't seem to locate any like it online!!! Thinking it was used as a customer gift when purchasing Mautz products. The stoneware crock has what they call a ball lock mechanism, holding either cheese or preserves of some kind. Neat advertising stoneware piece..and hard to find!!! Love the cobalt blue marking. Perfect for kitchen display or mix in with your primitives in your living room, etc. Use for a clever storage solution as well!!! Plus it will hold its value and is a good investment! Size is 6 1/2" high x 5 1/2" diameter. Only 1 Available.
