A self-adhesive bulletin board assembly includes a bulletin board with a surface coated with a first adhesive layer that is adapted to be attached to a support surface, and a transparent sheet with opposite first and second surfaces that are coated with second and third adhesive layers, respectively. The transparent sheet is sandwiched between first and second protecting sheets prior to attachment of the same to the bulletin board, and is capable of visually exposing the bulletin board when removed from the first and second protecting sheets and attached to the bulletin board by one of the second and third adhesive layers.
