To simplify catalogue sending operation by a method wherein a delivery form on which customer information is stated and a postcard on which the customer information is stated in the same way are integrated in a preliminarily separable state.

A delivery form 4 wherein reply destination information 8 is provided on a display surface of a postcard front sheet 2, a reply information entry column 10 and intrinsic information 11 of a reply person are provided to a display surface of a postcard rear sheet 3, and sending out information 15 of the postcard is provided on the postcard front sheet 2 or the postcard rear sheet 3, is separably fitted. Since the postcard having preliminarily reply destination information 8 and intrinsic information 11 of the reply person and the delivery form on which sending out information 15 of the postcard is provided are separably integrated, confirmation by checking of both comes not to be required. The postcard suffices the purpose only by being put into a packaging material together with a booklet such as a catalogue or the like, and its delivery operation comes to be very simple.
