                        board operated by a partially or fully
                        inflatable hose-spring combination that
                        in its state of rest automatically rolls

                        The invention consists of a
                        plastic hose with a flat spring strip
                        fastened at one side and a flexible
                        plastic sheet, with the desired
                        advertisement, fastened at the other side
                        of the hose. In its state of rest the
                        flat spring is rolled up together with
                        the plastic hose and the plastic sheet
                        that contains the advertisement, keeping
                        all in rolled up position. Blowing up the
                        hose with air it unrolls and remains in
                        straightened state as long as the
                        pressure difference prevails but if the
                        pressure drops down it rolls up again by
                        itself. The design, arrangement, shape
                        and number of the hose(s) used can at
                        will be modified.
