Albrecht Dürer was an apprentice with Wolgemut from 1486 to 1489, so may well have participated in designing some of the illustrations for the specialist craftsmen (called "formschneiders") who cut the blocks, onto which the design had been drawn, or a drawing glued. From 1490 to 1494 Dürer was traveling. A drawing by Wolgemut for the elaborate frontispiece, dated 1490, is in the British Museum. While some art experts may claim to be able to identify which Nuremberg Chronicle woodcuts may be attributed to Dürer, there is no consensus. Dürer was not yet using his monogram, and no artists in Wolgemut's studio signed their work in the Chronicle.
