The image is a photograph of a sign on a gray wall. The sign is rectangular in shape and has a white background with black text. The text reads "Fernand Knopff 1858-1921" and "I lock my door upon myself | 1891". Below the text, there is a smaller text that reads "1892 auf der Jahresausstellung im München Blasplast vom Kunstler erwenden | Nr. 79921". The sign appears to be a reference to the author's name and the year of birth.
