Graniton, a Czech factory founded in 1907 in Svijany-Podolí by Josef Rydl and Karel Thon and closed in 1928, which production has been recently rediscovered, collaborated with prestigious artists. Its production includes several sought-after cubist pieces, notably by Pavel Janák.
Here is a rare art nouveau piece.
Stamp and number intaglio on the reverse.
Very good condition - two small chips around the edge.
