Károly Koffán was an outstanding personality of Hungarian fine arts, Hungarian photography and ornitology. At least two generations have grown up without having encountered with the original works of Koffán. The Hungarian Museum of Photography has by his sons favour received the legacy of Károly Koffán, which consists of 70.000 items. We present the processed legacy to the public in the form of an exhibition, and we also publish a book on his works.
