The Crucifixion with St. John the Baptist and St. Dominic [?]

A pen and ink drawing in a triangular composition of the scene of Crucifixion. Jesus on the cross is in the centre of the canvas, at the pinnacle of the triangle, flanked by two standing figures -- St. John the Baptist on the left accompanied by his attribute a lamb and holding a cross on his left hand, and another saint [St. Dominic?] on the right in a monk's habit. A town in the distance is faintly sketched. Paper has been cut around central crucifix shape and standing figures pasted back together on to the same sheet.
