The present invention relates to a signboard for advertising, comprising: a channel which is secured to a wall and on the inside of which is housed a light or the like; a perforated board of which the bottom is joined to the upper part of the channel, and on the front surface of which are formed a plurality of perforations; and an advertising graphic sign or symbol joined to perforations of the perforated boards. Consequently, replacing the signboard involves no more than loosening a securing nut, extracting a male screw part of the advertising graphic sign or symbol from the perforations and replacing just the advertising graphic sign or symbol, and hence it is very easy to erect and take off signboards and no damage at all is caused to the appearance of buildings even if signboards are frequently erected and taken off as businesses are regularly replaced. |
