From the 1985 story 'Attack of the Cybermen', starring Colin Baker as the Doctor, comes this fantastic principal and prominently featured alien 'Cryon' full head mask and neck ring.
Subsequent to filming, the head was formerly on display at the official BBC Doctor Who Exhibition in Blackpool, England, and remains presented today as it was then.
Despite the fragile nature of it's construction the impressive translucent full head mask and companion neck ring have survived very well and it only exhibits slight signs of age.
Original alien/monster character items such as this are very difficult to source from the iconic Doctor Who Television Series, the world's longest running science fiction television series.
A truly wonderful and important piece of Doctor Who history.
