Rubens, Peter Paul – Study of the head man, looking upward, hands and part of the male profile Hermitage ~ part 10

The picture has something of this: paper, texture, vintage, page, retro, antique, abstract, parchment, sepia pigment, design, ancient, blank, sooty, rough.
Perhaps it’s a drawing of a man’s head with his eyes closed and his hand resting on his chin, with another man’s head in the background.
