GB 1966 Christmas ERROR White Eyes & Blue Colour Shift Lightly Hinged.

On offer 1966 Christmas stamp showing white eyes instead of black eyes as shown on right hand stamp. There also appears to be a lack of blue top left corner and below neck.

Apologies in advance should the description be incorrect as my knowledge of stamps is limited.

UK buyers only please unless using Global Shipping Programme.

Please see photos and thank you for looking.
