POSTER REX was founded in 2014 by the graphic designers Lars Harmsen (Munich) and Markus Lange (Leipzig) from Studio Farn. For each session, they invite an artist to create unique posters, produced in different silkscreen workshops around the globe. All posters are silkscreen printed by hand or with other digital or analog techniques. Each session has its own topic. POSTER REX also offers workshops for students. By now, the collection counts over 1.500 unique posters. A set of posters have been curated for exhibitions.

Lars Harmsen (Munich) and Markus Lange (Leipzig) from Studio Farn met the first time when they gave the Arial-workshop at the University of applied sciences Dortmund, where Harmsen is Professor for editorial design and typography. Half a year later they worked together on the SLANTED Cuba issue, published in 2013. Along, a series of posters have been printed, each of them being a unique piece, playing with accidents that occur due to random overprinting. The series was awarded by the TDC NY. In summer 2014, Lars and Markus returned to Havanna to see all the designers they met a year before. For three days they printed posters in a small printshop in the centre of Havanna, mixing Salsa with Bauhaus. The idea for POSTER REX was born.
