A fine used 1d Star lettered RF cancelled by a Dublin duplex on a cover to Enniskillen. Back-stamped by a fine rare ‘Trollope’ cancel for ENNISKILLEN ‘ENNNISKILLEN/A/FE 28/63‘. These experimental cancels were the brainchild of Victorian novelist Anthony Trollope – who was also an Inspector at the Post Office. It follows the Continental double ring style. Only two were issued: one for Kingstown and one for Enniskillen. No contents.
