Two individually decorated vases by the Dutch company Sphinx in Maastricht, 1950s.
The undertone is orange and the top glaze is white. After turning them they have been hand decorated by an engraved pattern inspired by Art Deco ornaments. This brings out the red color from the underneath layer.
Both vases have the same pattern but their size are different.
The tall one; height 34, width 28 cm
The smallest one; height 28, width 20 cm and is a tone lighter.
