Pipa, Inc. appointed Ana as its agent in connection with the company's business and advertised the appointment in a newspaper. Before the advertisement, Tony, a client who happened to drop by, was informed of the appointment which was revoked also by advertisement after a few months. A week later, Tony entered into a contract with Ana as an agent of Pipa, Inc. Now, Tony seeks to make Pipa, Inc. liable. Can Tony recover from Pipa, Inc?
