Charming ceramic plate/ashtray from the 1970s with Op-Art decoration in concentric circles in brown, orange, yellow, white and black tones. The lowered shape with a wide rounded edge highlights the central graphic design, typical of German WGP ceramics of the period. Unbranded specimen, attributable in style and technique to the Bay /Dümler & Breiden / Jasba area. Excellent as a centerpiece, pocket emptier or pop accent in mid-century interiors. Normal signs of aging; shiny and well-preserved enamels.
