Sketch of the right-hand half of an altar

Sketchy drawing of the right-hand half of an altar: above the tabernacle (?) is a saint pointing a cross forwards in his right hand; another figure is seated to the right of this. The altar has been finished on the right-hand side with a tall pilaster, descending from which is a drape and against which another volute is set. The drawing is enclosed at the top by a half arch.
