The Bellman (segment of an illustration by Henry Holliday to Lewis Carroll's The Hunting of the Snark) and a mirrored view of an unfinished portrait of Sir Henry Lee by Marcus Gheeraerts the Younger

Yes, the noses and the eyes are different. This is not a face comparison. In this case, Holiday's pictorial allusions refer to the surroundings of Lee's face, not to the face itself. As in several other cases, Holiday maintained the topological relation between the quoted shapes. Here the shapes are the nodes in two quite similar graphs.

Holiday even "copied" the cracks in the varnish of Gheerert's painting.
