Vintage Green Stoneware Swimming Fish Concentric Circles Saucer 6.5"

Vintage Green Stoneware Swimming Fish Concentric Circles Saucer 6.5" No maker's mark. I've seen this attributed to Buffalo China but haven't been able to verify. I was unable to find a matching cup. This would make a unique base for a pillar candle or a planter as well as serving as a trinket dish. Pre-owned, excellent used condition. No chips, cracks, crazing, or other damage. Ships from a smoke-free home, packed with care.
