The monogram has been added by the late 16th Century Strasburg chronicler and occasional artist, Sebald Büheler (1529-1595). He inherited Baldung's estate through Nicolaus Kremer, Büheler's brother-in-law and a pupil of Baldung who had purchased it from the artist's widow. Drawings from his collection can be recognised by the spurious monograms he added, and he often inscribed the sheets at the lower edge. Although his attributions are often wrong, Büheler's Collection is a rich source of Upper Rhenish drawings which have been widely dispersed, although both the Albertina and the Kupferstichkabinett, Coburg have large groups of studies from this provenance. The number of designs for stained glass in his collection, often with heraldic arms, reflect his interest in chronicling the Alsatian nobility, and they must have been useful in the creation of his armorial albums that he formed in the 1580s.
The present drawing is probably a design for a small secular glass panel. These Kabinettscheiben (cabinet pieces) decorated civic halls, guild chambers and private houses and were usually gifts from individuals or organizations whose arms appear in the design. The designs were a collaboration between the artist and the glass painter, with the red chalk lines, as in the present drawing, added by the latter to give an idea of the leading which would hold the glass together. The most detailed account of the process is given by Christiane Anderson, Early German Drawings at Coburg, in From a Mighty Fortress, Prints, Drawings, and Books in the Age of Luther 1483-1546, Detroit, 1983, pp. 53-5
