Artful Dodger mentioned in Chapter 24

[Melanie]

I can't find anyone else who has mentioned or caught this reference, but I am currently reading the book, and in Chapter 24 when Wemmick is explaining the creepy face casts in Jagger's office, he says this of the first cast:
“These are two celebrated ones. Famous clients of ours that got us a world of credit. This chap (why you must have come down in the night and been peeping into the inkstand, to get this blot upon your eyebrow, you old rascal!) murdered his master, and, considering that he wasn’t brought up to evidence, didn’t plan it badly.” “Is it like him?” I asked, recoiling from the the brute, as Wemmick spat upon his eyebrow and gave it a rub with his sleeve. "Like him? It's himself, you know. The cast was made in Newgate, directly after he was taken down. You had a particular fancy for me, hadn’t you, Old Artful?” said Wemmick.

I can't help thinking that the reference to "Old Artful" wasn't completely deliberate on the part of Dickens. What do you think?
