SPECTRE

This Blofeld is authentic to Fleming's novels because he is Polish and realizes the importance of information and also to the Connery films because:

he presides at a SPECTRE meeting with his face in shadow;

the meeting pauses and everyone stands when he enters;

he acquires a disfiguring facial scar across one eye;

in an impressive SPECTRE headquarters, he addresses Bond from off-stage before entering to meet him in person - like Doctor No who, in the films, was also a SPECTRE operative.

Addendum, 18 November 2015: The octopus rings are also authentic to the Connery films.
