Drawing of an altar

Quick sketch of the left-hand half of an altar: there is a tomb altar, above which a painting full of figures is placed; above this is a depiction of the Madonna and Child, while a saint kneels before her; to the left of this, the altar leans forwards slightly: it concerns a plaque between two columns, on which there is medallion held upright by two figures. The whole is spanned by a drape.
