Nothing represents a piece of history better than a piece of the Berlin wall, and it became very popular once it was reduced to rubble - albeit that with the smaller pieces it can be difficult to prove what they are.
Now online charity auctioneer CharityBuzz is selling a segment of the wall rendered as an artwork: the remarkable Rectangles in Rainbow.
The "Grenzmauer 75" (Border Wall 75) in segment construction was part of the inner city Berlin Wall. Specifically, this make was the fourth generation of Berlin Wall segments, with special features, such as the lateral curbs and the metal edge on top.
The L- and T-segments are of the type which marked the city centre frontier between Berlin-West and -East at Potsdamer Platz and Brandenburg Gate.
The present elements were pulled down from the southern city frontier at Teltow and from Falkensee and stored by a building firm, which was involved in the buildings works for the new construction of Potsdamer Platz, for the artist group Luxpopart Patrice Lux in the south of Berlin.
Consequently, the origin of these pieces can be documented up to today without any gaps.
In 2008, the Axel Springer AG acquired 34 elements of Patrice Lux.
Some of these segments became part of the 2008 built wall memorial by the artist Stefan Balkenhol for Axel Springer AG.
The proceeds of the auction will benefit Cinema for Peace, and the lot is expected to sell for up to $40,000, though any collectors interested should be warned that they will have to transport the exhibit from Germany. Bidding ends October 13.
