A bit off topic but as slavery has been mentioned. The sculptures at the entrance to the Martins bank buildings on Water St show a merchant pressing his hands down onto the heads of two African boys. I was led to believe this was to do with slavery. Frank Carlyle in Liverpool unseen gives the opposite account mentioning what they are carrying and says that it signifies that the prosperity of the city and this building in particular being a bank is helping the lesser poorer nations? Anyone got the real take on it?
