Abstract: This invention relates generally to signs such as are used for house numbers, door plaques, and other identification items, and particularly to the type of signs in which the number or letters are removable and replaceable. The novelty of this invention resides in all the components, such as the outer frame, the background, and the numbers, letters, or symbols, being replaceable or interchangeable. The above mentioned components of the sign are combined by simple press fitting, or by means of a set of screws which are also used to attach the said sign to a wall or similar surfaces.
