Written out of history
This is a fantastic Lawrence image of the O'Connell Monument, on what was then Sackville Street in Dublin. But what's fascinating is the excision of the two characters who were obviously taking their ease on the steps of the plinth...
Wanted to date this accurately, and was hoping that the shops on the left (Elvery's Elephant, etc.) would help us to do that. The monument was unveiled in 1882. From staining on the steps, it looks as if it'd been in situ for a while. I started the bidding at 1885, but see below comments for a tour de force example of dating detective work, especially from MKSeery.
