Abstract:
A sign displaying characters in a manner emulating a digital display, in that the characters are formed using character elements to define parts of a particular font of characters. However, unlike a digital character that uses electrical control to activate character elements making up particular characters in the font, the present sign defines particular characters by covering the character elements not required for that character. The digital characters are formed on one or more sign inserts that removably fit within a sign body. The sign body includes a window exposing to view the character elements of each insert. The sign inserts may be of ferrous material and the cover members of magnetic material attachable to the inserts, so that the cover members are readily repositionable to change the message displayed by the digital characters.
