Blue Plaque in Eastbourne.

From Wiki:
"The benefactor of the plaque to Charles Dickens was the Chairperson of the Eastbourne Dickensians, the late Vera Banwell-Clode: it records the author’s visits during the 1830s, when he stayed as a guest of the Victorian artist Augustus Egg, RA, who rented the house in Borough Lane."
