The artist's style appears to have changed dramatically around 1485; the drapery of his figures became more sculptural, separated into broad planes like contemporary wood sculptures, as opposed to his earlier and more fluid style. This has generated speculation among scholars that some of these later prints were either designs for wood relief sculptures, or were based upon reliefs that are now lost. This is partially supported by records that Johan van den Minnesten was commissioned to paint several relief sculptures. His most involved work was a series of passion engravings, of which only The Last Supper, The Agony in the Garden, and The Betrayal of Christ survive. List of works Dimensions given are that of the image. The essence of printmaking is the production of multiple images, so most of these works exist in more than one copy and are in the collections of several museums. As with most 15th-century prints, surviving impressions of his works are rare - the three Passion prints survive in 8,8 and 20 impressions only. The works can only be approximately dated, if at all, because so little is known about Master I. A. M.'s life. None of the prints were titled, so they are given generic or descriptive titles that vary slightly between sources. The individual impressions also vary in sheet size.
