The sitter was town clerk of Landshut in Bavaria between 1464 and 1488. He is identified by the letter he holds, which is addressed to him. On his ring is the device of a moor's head, which may be a pun on the first syllable of his name. The background against which the sitter is shown is a wood grain, not uncommon in German portraits from the period.
The original top edge of the painting has been cut slightly. The artist, who may have been Tyrolean, is named after this picture.
