Postcards and letter-writing paper in all formats, all shapes and of all materials and on all subjects, made in the form of jigsaw puzzles

摘要

These postcards and this letter-writing paper in jigsaw form use both traditional subjects and strictly humorous subjects, photographic illustrations and watermark processes. The sender writes his message on a jigsaw postcard or on letter-writing paper and sends it in an envelope to the addressee. The addressee of the jigsaw postcard or letter-writing paper will see the jigsaw break up when opened and in order to reconstruct the message from the sender must reconstruct the jigsaw postcard or letter-writing paper. The innovation lies in the simultaneous use of a postcard or letter-writing paper and a jigsaw puzzle.
