Charles Greber sandstone lamp base

Sandstone lamp base by charles greber (1853-1935). Pretty lamp base in flamed sandstone with blue, white and gray shades on a green background. Signed under the base c greber and marked on the lamp: cologne, cyprus, paris. In very good and functional condition. No cracks, note a small chip on the collar but not very visible. Bayonet bulb and lampshade not supplied. Quite heavy since it is weighted with sand and therefore very stable. Height with the socket: 28cm.
