The plates feature the traditional block-lettered "PYREX" logo contained inside a central circle. All-caps lettering indicates an authentic, vintage piece made before the brand transitioned to lowercase lettering in 1998. These specific Pyrex amber glass pie plates were manufactured from the late 1970s through the 1990s.
