Vintage ceramic whale tankard with mermaid in the bottom

Awesome but very different tankard in the shape of a whale. Measures 8 3/4" tall, and made of glazed ceramic. No makers mark or sticker, Probably is about a litre. I thought at first it was a vase but if you look inside at the very bottom, there is a tiny mermaid molded into the tankard. Tiny pinhead size glaze pop on the white part but otherwise pristine. Hand painted eyes, and all decoration underglaze. A perfect and unique unusual gift for someone who loves whales or ocean related things. See all the other dolphins and whale items I will be listing.
