Very cool variant of the famous Saar tinnie which I have never seen before. The Saar, of course, was an industrialized region of Germany occupied by order of the Versailles Treaty. The Germans were increasingly resentful of this occupation. This tinnie shows smoke stacks shrouded by exhaust clouds which become hands with fingers raised if looked at correctly. These hands/smokestacks are bound in chains. Backmarked GLASER & SOHN DRESDEN. Solid, heavy metal construction much better made then typical tinnies. Very cool, very scarce tinnie.
