Builder's signature
A builder's signature, sometimes known as a craftsman's signature, tradesman's signature, or workman's signature, is a type of signature associated with several skilled trades in which a tradesperson inscribes their name on a structure during or after completion of a project. In some instances, the signature may be hidden from public view, such as a signature inscribed on wooden framing which is subsequently covered with drywall; in other instances the signature may be prominently displayed such as in concrete.
