Lovely old sign in the Argyll Arcade in Glasgow. Damp pedestrians must have caused severe blocking incidents for this sign to be erected. Argyll Arcade is one of the oldest in Europe. Built in 1827, it's a beautiful place, crammed with jewellers and diamond merchants. It was designed by John Baird, whose other work seems to have been more spiritual (churches and university buildings, for instance). It's stunning, and worth a visit.
