ABSTRACT:
An expandable balloon wrapped media display system including: a transparent balloon (30); an accordion pleated sheet (11, 11a, 11b) having formed thereon a message, picture, graphic display, graphic design, or combination thereof; a first attachment member (15) fixedly secured to a first edge (21) of the sheet (11, 11a); the sheet (11, 11a, 11b) being folded up on itself at its midpoint (28) so as to present the left and right halves (26L, 26R) of a second edge (26) thereof in generally face-to-face relation; a second attachment member (22) having a tubular portion (24) and an axially extending flange (25) fixedly secured to a second edge (26) of the sheet (11, 11b); the folded accordion pleated sheet (11, 11a, 11b) being inserted into a balloon (30) with the first attachment member (15) engaging the polar extremity (34) of the balloon (30) most remote from the balloon's inflation aperture (31) and the second attachment member (22) having its tubular portion (24) disposed within the constricted neck portion (32) of the balloon (30); first attachment means (35) securing the first polar extremity (34) of the balloon (30) to the first attachment member (15); and, second attachment means (26) securing the constricted neck portion (32) of the balloon (30) to the tubular member (24), whereupon inflation of the balloon (30) causes its sidewall to stretch and enlarge, thus causing the first and second attachment members (15, 22) to move away from one another so as to unfold the accordion pleated sheet (11, 11a, 11b) and thus expose the media formed thereon to observers through the balloon's transparent sidewall.
