Very cool Vintage Tankard/Mug by Jasba. A great example of West German Art Pottery, this piece features a Mid-Century Modern incised design. Nice glazed finish. Marked on the bottom with item #400514. I think the color can best be described as olive green. In excellent vintage condition - there is some light crazing that is common in pieces that are this old (see photos). Mug measures 5.5" tall and just over 3" at mug opening.
