Secret Service Picture Library #4 is a Page Publications edition of MV Features' Secret Service Picture Library #22:
The Page Publications edition features a Keith Chatto cover. It is not based on interior art. I'm betting there's an earlier issue in this series with a Chatto cover swiped from the UK cover above - that's my verdict! TBC.
Love the vintage headphones and the reel to reel tape player on the Chatto cover. And the balding bureaucrat with the red tie. Wonder whose side he's on...?
