Anchor
An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin "ancora", which itself comes from the Greek ἄγκυρα ("ankura").
Anchor Stone Blocks
Although Anchor Stones survived World War I and World War II, the factory was included within Communist East Germany when the Iron Curtain divided Europe. In 1953, the company was nationalized as VEB Anker-Steinbaukasten, a state-owned company. In 1963, the production of the blocks was stopped. The trademark "Anker" was used by various toy companies in East Germany, none of which were related to the stone building set factory.
