As the old song says "All the nice girls love a sailor" or at least the anonymous sender of this pretty card did. I wonder if he could guess who had sent it?
The lucky recipient was Mr H. Noble, an engineer on SS 'Manchester Importer' one of Manchester Liners ships which travelled back and forth from the Manchester Ship Canal to the eastern seaboard of the USA and Canada. The card comes from Rhyl (dated 17th October 1906), a popular Welsh seaside resort at the time and the heart is winging its way to a ship moored on Salford Docks
It could be one of these. The Manchester and Salford Docks closed in 1982.
