- [upper inset]: Henry Holiday’s depiction of the Billiard marker in Lewis Carroll’s The Hunting of the Snark (1876).
- [background]: Henry George Liddell (painted by Sir Hubert von Herkomer in 1891, probably based on a photo). Liddell was Carroll’s (Dodgson’s) superior in Christ Church, Oxford. He also was the father of the “real” Alice, so to speak. As for the time line, of course Holiday could not have alluded to this painting (of which a vectorized grey shade version is shown here). (There also is a photo.)
- [lower inset]: The comparison shows Henry Holiday’s first depiction (draft) of the Billiard marker in Lewis Carroll’s The Hunting of the Snark. The face on the right side is Henry George Liddell’s face at a younger age. Here both noses look quite similar.
I think that in his first draft, Henry Holiday alluded to the image of the young Liddell when he created his depiction of the Billiard marker. However, as Liddell was the boss of C. L. Dodgson (aka Lewis Carroll), I could imagine that in the view of Dodgson, the similarity was too clear. Thus, the final depiction of the Billiard marker was ambiguous enough not to get Dodgson/Carroll into trouble.
