Bycatch (but not mine):
[left]: John Tenniel: Alice on the Train (1872)
[right]: Augustus Leopold Egg: The Travelling Companions (1862)
I found the comparison in preraphaelitesisterhood.com. If it is a pictorial reference at all, it might be a nice pun by Tenniel, but not as challenging as Henry Holiday’s conundrums.
Playing with the work of other artists could have been fun for John Tenniel too. (Of course another reason for such similarities always could be, that Holiday and Egg both referred an image by a third artist.)

Bycatch from my Snark hunt:

In the introduction to The Hunting of the Snark (Penguin Classics edition, 1962, 1974,p. 17), Martin Gardner wrote:
How well the academician Holiday succeeded in producing grotesques for the Snark (it is the only work of Carroll’s that he illustrated) is open to debate. Ruskin was certainly right in thinking him inferior to Tenniel. His drawings are, of course, thoroughly realistic except for the overzize heads and the slightly surrealist quality that derives less from the artist’s imagination than from the fact that he was illustrating a surrealist poem.
I think that Gardner certainly was wrong. And Ruskin certainly was wrong as well. But, of course, that is open to debate.
