Offenbach. On Friday, the Siegen-based fine art photographer Thomas Kellner opened his exhibition Tango Metropolis at the Kunstverein in Offenbach. Kellner used the catalogue, which was published at the end of 2016 by the Siegerland Artists' Association for presentation at the Siegerland Museum, to successfully apply to the Kunstverein. Further stops this year will be the Stadtmuseum in Freudenberg and the Kunstverein Emmerich. The exhibition in Frankfurt, together with the sculptor Miro Karaczun, can be seen until March 14,2018
