An air sign balloon having a planar display surface is provided to prevent a distortion of an advertisement image by displaying the advertisement image on planes of a polygonal column. An air sign balloon includes a mount(110), plural support air columns(120), a display sheet(140) and a fan. The support air columns are made of a flexible material and formed in a tube-like shape. Bottom portions of the support air columns are expanded into a circular column shape by an inlet air pressure. The display sheet is made of the flexible material and formed in a sheet-like shape. The display sheet is implemented to be supported by the support air column, such that an expanded side surface is formed between the support air columns. An advertisement image is displayed on the side surface of the display sheet. The fan blows air into the support air columns. |
