Four bowls free-form cups with French metal enamel

The bowls are in perfect condition, no gaps, no cracks or splinters. Free-form, graceful and pure, approaching the drawing of a sheet. Very beautiful shimmering metal enamel, warm colors, from intense vermilion red to golden yellow for the interior, and metallic black for the underside. Great speckled effects. The pieces are marked on the reverse at the tip under enamel. This is a french production from the 60s.
