The letter form has two halves (1, 2) one of which contains a form part (13), e.g. a post office paying-in slip, which can be separated along a peripheral line of weakness (5). The other half has a window (3) which makes an area (4) on the form part (13) visible, which area (4) is intended for the address of the recipient. Adhesive strips (12) on the one half (1) allow the two halves (1, 2) to be bonded when they have been folded together to form a letter ready for mailing. By means of perforated lateral edge strips, a large number of letter forms can be connected to form a supply roll which can be labelled in suitable booking machines. <IMAGE> |
