Abstract
Abstract A signboard of a type used to carry replaceable letters or similar indicia can be improved by using at least one easily operated holder to connect the signboard to a support such as a wall. This permits the signboard to be easily removed from the support so that it can be held in a convenient manner as the content of a sign on the signboard is changed or altered.
