Celestial globe marked with Edwin Hammar Stockholm and manufactured by Columbusverlag, Berlin, Germany. The mouth-blown glass globe is hand-covered with lighting and a compass in the base, which is typical for the globes from this time. This globe is a very rare specimen from the 20s and 30s. It was made without a meridian and can be rotated on the wooden base. The globe has an E27 socket. In the middle of the 20's Columbus produced the first illuminated globes. The glass balls are mouth-blown. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
