Darwin's Study and the Baker's Uncle

This is about a possible allusion by Alfred Parsons to Henry Holiday.

The comparison of these two images started in June 2010. Alfred Parsons may have alluded to Henry Holiday's illustration. I am not so sure about that, but if Parson played Holiday's game with Holiday's illustration, then Parsons must have manipulated the reality of Darwin's study a bit.
