I believe this is the Sun Inn, in Knowles Street, Stockton. Some of the building features are clearly still on view today, but the archway and the sign along the roof line, advertising Dents (Dents what?), are no longer visible on today’s building. Possibly the Dents sign was a wooden board that could be easily removed. I have no idea who the two gents or the child are, and there is no date.
