Here is another piece that I especially liked from the Ai Weiwei exhibit in Martin Gropius Bau. Apparently Weiwei was invited to build an art studio in Shanghai. In a cruel twist of fate, the government then destroyed the studio without giving the artist any reason as to why.
A closer look at the stamping details on some of the bricks that were saved. For more "rubbish" take a look at Rubbish Tuesday. Here is some additional information on the work from the sign:
"Souvenir from Shanghai: 2012, Concrete and brick rubble from Ai Weiwei's destroyed Shanghai studio, rosewood bedframe from Qing dynasty
In mid-January, demolition of the building started without warning. The work Souvenir from Shanghai is made from material from the site."
