The artwork composed of Z3 traffic signs is located in Prague 5 – Na Knizeci. The installation took place in 2016. The form of the mosaic refers to the abstract art of the 1960s. It is situated on a blank wall of a house directed at an empty plot, designated for future development. The whole concept and placement of the piece focuses on contemporary visuality of the public space, and thus offers a reflection with a view to the past.
