Wolfgang Beurer was identified on the basis of a number of prints signed with the initials W.B. with an entwined serpent. This discovery was used by Buchner in 1927 as the starting-point for establishing the artistic identity of this anonymous master whose prints had previously been considered reworkings of compositions by another artist. In 1985 Anzelewsky identified W.B. as Wolfgang Beurer on the basis of a drawing of A Man on Horseback in the Muzeum Narodowe in Gdansk, which is dated 1484 and has annotations by Dürer.
Among the works that have been attributed to Beurer is Portrait of a Man, on whose reverse is a depiction of a figure with a coat-of-arms (Museo Thyssen-Bornemisza, Madrid).
