Four more space invaders! So, clockwise from top left; Union jack space invader near the hairdressers on the way from market street to the CIS; Large inverse space invader on Faraday Street (off Lever Street), Yellow out-of-focus space invader above withy grove stores sort of round the back of the Printworks; and lastly one right on the front of an old bank on the corner of Princess Street and Portland Street.
