Wings: Portraits of Two Donors, verso ; Central panel: Virgin and Child (Chrysler Museum of Art, Norfolk, Virginia, 71.491), Wings: Portraits of Two Donors. Although today there is an incongruity in dimensions between the fragmentary center panel in the Chrysler Museum and the intact wings shown here as well as differences in the scale of the figures, originally they likely formed a triptych. Together, the space of the center panel and the right wing form one continuous room. The left wing does not relate to the center panel in the same way. A possible explanation is that the male donor is still part of our world while his wife has passed away and thus inhabits the same realm as the Virgin and her son. That the donor wings had a memorial function is confirmed by the verses written on pieces of paper "pasted" onto the painted imitation marble backsides of the panels with blotches of red wax (seen here).
