Similar images from the Tree-man can be seen in The Alberta in Vienna (probably the original), the Rijksmuseum in Amsterdam (RP-P-1882 - A-6534) and in The Museum Boijmans van Beuningen in Rotterdam (BdH 9588(PK).
According the Museum: Round image in a rectangular plate. Depiction based on Bosch's drawing in the Albertina in Vienna and the depiction of hell on the right panel of the painting "The Garden of Earthly Delights" in the Prado. In the center we see a grotesque figure, half human, half tree, with an open egg-shaped abdomen. His head is that of a human. Both legs, however, are tree trunks, each resting on a boat in the water of an estuary, the whole in a panoramic landscape. On the head of the figure is a bowl with a jug from which males climb. The abdomen is open and resembles a broken eggshell. There is a company sitting at a table like in an inn. Furthermore, on the body are dry branches with birds including an owl, as well as a flag with a crescent moon. The large figure is amazed and amused by various characters: at the bottom is a painter with his brushes embracing a woman with a dog. They turn to the viewer while she points to the monster. Next to her is a scientist who takes measurements. To the right of a rock, another group of people and children are watching. Unlike the painting in the Prado, this is not a depiction of a satanic figure in hell, but - like the drawing in Vienna - it is a curious, fantastic image in itself.
