Sigmar Polke: Objects: Real and Imagined

One potato, two potato, three potato, four... not many artists think to make art from spuds (not counting the many masterpieces executed by under-5s using them for printing). But then Sigmar Polke wasn't 'many artists'. This exhibition focuses on the early years of the East German's career and features the sculptures 'Potato House' and 'Potato Machine', along with many works on paper. They look better than a chip tastes.
