In Richmond Locomotive & Machine Works v. Moragne, 119 Ala. 80, 24 So. 834 (1898) the Court wrote: "If a principal is not disclosed ..., and the party signing describes himself as agent, trustee, or the like, without more, it is the obligation alone of the party whose name is set to the paper, the superadded word or words being mere descriptio personae to be disregarded as surplusage, and evidence cannot be received to show that he was, in fact, the agent or trustee or the like of an undisclosed principal, cestui que trust or the like, and that the obligation was that of such other person." (119 Ala. at 83, 24 So. at 834.)
