Tif et Tondu (Tif and Tondu) is a Belgian comic strip about a duo of private investigators, originally created, written and drawn by Fernand Dineur. Several artists and writers have worked on the series but the most popular version is that drawn by Will, with writers Maurice Rosy, Maurice Tillieux, and Stephen Desberg. The strip first started in 1938 and lasted until 1997, just one year short of its 60th birthday. Source: Wikipedia (en)
