July 1 - August 15, 2015
Belgrade, Serbia

The LBTB was exhibited in Belgrade, the capital of Serbia, in one of the main Belgrade's square "Nikola Pasic". The 42 posters were out day and night for almost two months (July 1 - August 15, 2015), and were seen by thousands of people. During this period, on July 10, there was a National day of Science in Serbia, and we had a whole day promotion of the exhibition, supported with science busking.

The exhibition was organized by the Faculty of Mathematics University of Belgrade, the National "Center for Promotion of Science", and the marketing agency "Marker", with the support of Serbian Astronomical Society, Serbian Physics Society, and Serbian Optics Society. We obtained the financial support from "Radijus Vektor" and "Kultur Akt".'
