The fence surrounding the construction zone for the new Wien Mitte train and U-Bahn station generally sports many colorful billboards. On one walk, I noticed the ads had been ripped off, presumably to make way for the next advertisements. The resulting patterns from the torn paper and residual glue reminded me of abstract paintings. In fact, as I've seen less pleasing art in museums and galleries, I thought it was a good idea to take a few photos of the ripped billboards. The stares and puzzled looks from passing travelers were quite funny. Oh well, I like the designs anyway.
