Anvia "Grasshopper" floorlamp

Rare floorlamp by J.J.M Hoogervorst. This model is made in very small series in the 1950's. The lamps were produced by the Dutch company Anvia. The uniqueness of this lamp lies in its base. It can be moved up and down to adjust the angle of the lamp. The lampshade can also be put in various positions.
This timeless model is a combination of aluminum and steel used.
 
The overall condition of the lamp is good however there is a small area (5mm) on the shade shows a spot, seen in the pictures. The lamp has the orginal label of 'Anvia'.
