Legal analysis: invalid, it is invalid without my signature and fingerprints. An agreement or contract signed by others with their fingerprints is valid as long as I admit that it is signed by an entrusted agent (with fingerprints), and vice versa.

Legal basis: Article 502 of the Civil Code of People's Republic of China (PRC), a contract established according to law shall come into effect upon its establishment, unless otherwise stipulated by law or agreed by the parties.
