Deenen Pottery, St Paul, MN Brown Speckled Mug 3D Duck ,applied to inner rim Handmade Ceramic, Matte finish, white wash glaze Approximate Measurements Height 4" to mug rim Rim Diameter 4" Pre-owned. Very Good Condition You will see some whitish spots and streaks - those are part of the glaze pattern I'm pretty sure this is vintage but I can't pinpoint when Deenen stopped making these type of mugs (e.g., fish, duck) not when I purchased it. 😊
