I found this among my photographs, and the quality is really very bad. I don’t remember where I got it or how to date it except that it was drawn in a period when Lear was staying at 15, Stratford Place, London and that it was made for William Holman Hunt:

O Pa! the Barry-Lorgon has begun for to play.

The cartoon is remarkably similar to a George du Maurier strip from Punch, 13 March 1869, but by the time it was published Lear had already left the rooms at 15, Stratford Pl. (Diary, 15 September 1868) and from that moment, when in London he stayed at 8 or 10 Duchess St.
