The preform preferably subsequently is blow-molded to form a container (20) having the raised indicia on an inside surface of the container. This raised indicia on the inside surface of the container may be viewed from outside of the container to confirm that the container is genuine. In accordance with various embodiments of the disclosure, the raised internal indicia may be on the bottom wall (24) , sidewall (25) , shoulder (26) and/or neck (28) of the container.
