This is bycatch from my Snark hunt and not related to Henry Holiday's illustrations.

Left: Segment of Maurits Cornelis #MCEscher's "#CiminoBarbarano", 1929 (in #Escher’s “Italian” period). This reproduction of the original print has been horizontally compressed and segments on the right side and of the left side of the image have been removed.

Right: Segment of #JohnMartin's "The #Bard", ca. 1817. In that grayscale reproduction, the segments on the top and the bottom have been removed.
