Vintage Pottery Mug 4" Tall Mallard Duck Beautiful Tri Color With Hand Painted Ducks 10 fl.oz.. Pre-owned but in new, never used condition. There is one white dot on the design but that is part of the glaze (couldn't clean it). I used to collect all kinds of coffee mugs (Otagiri mugs were my personal favorites) and it is time to thin my hoard. Please refer to the pictures for the item condition and size.
