Map Jigsaw Centred On Your Home, These unique jigsaw puzzles are centred on the place of your choice.

The 255-piece puzzle measures 14" x 11" and the 400-piece puzzle measures 12½" x 18½", when assembled. For that added personal touch, there is an area on the box for you to write a title, description or message. Please specify the full postcode of the property you would like at the centre of the puzzle. NB no Eire or Northern Ireland.
