This postcard of Riley's Pianos on Constitution Hill suggests there was not only a piano/harmonium shop but also a Hall. I presume Riley's Hall must have been over the shop. I had a look on Streetview to see if the building is still there and, joy of joys YES! How chuffed I was to see it's still there and not in too bad nick either. Seems that quite a few Victorian buildings have survived along Constitution Hill/Great Hampton Street, although many frontages have suffered over time. Good to see many of the original decorative features of the Riley's building have survived.Viv.
