Virgin and Child with Saints , a drawing in Stockholm 's Nationalmuseum , is believed to be a study of a portion of the original altarpiece by a follower of van der Weyden , who possibly may have been the Master of the Koberger Ründblatter . The drawing have a loosely sketched background and shows , from left to right : an unidentified bishop saint with mitre and crosier making a blessing gesture ; a narrow gap with a few wavy vertical lines suggesting a start at the outline of a further kneeling figure ; a barefoot bearded figure in a rough robe identified as Saint John the Baptist ; a seated Virgin holding on her lap the Christ Child who lean to the right , looking at a book ; and holding the book , a kneeling beardless male identified as John the Evangelist . The drawing stops at the end of John 's robe , at about the point on the London panel where Joseph 's walking stick meet John and the Magdalene 's robes . This suggest that the Magdalene panel was the first to be cut from the larger work .
