Update: originally another building stood next to Capons. As its upper storeys were slightly set back from its neighbour's façade, it left enough space on the side wall for Capon to advertise his trade as pictures taken in the mid-1950s show (here and here. Note that back then the signs were different). This building was demolished when the road was widened.
