Purple ceramic shell lamp 1970

Purple ceramic shell lamp and white opaline ball dating from the 70s. The purple color is by far the rarest. Height 19cm. Depth 18.5cm. Width 18.5cm. In good condition, clean and in perfect working order. Small base e14 screw socket - delivered with bulb. A barely visible micro chip. Another identical shell lamp but pink in color is on sale in my shop (see the last photo). Sent in very careful packaging.
