Paul Emsley's portrait of the Duchess of Cambridge represents the final stage of preparation before she leaves Earth to pilot Thunderbird 5.
'The flashing eyes go in this weekend, and then it's off to Tracey Island to hang on Jeff Tracey's study wall,' said Emsley.
The decision to put the Duchess on secondment to International Rescue was made by the Queen so that Kate could wait out her pregnancy in untroubled isolation, but still take part in royal duties, serving the Commonwealth.
'She'll be monitoring the emergency radio channels and stuff, so if anything kicks off in the world, she'll be the first to know, and we can respond to avert death and disaster,' said Jeff Tracey.
Gordon Tracey will pilot Thunderbird 3 to take the Duchess to the IR space station.
'There'll be a short wait for Her Royal Highness once we've docked while we load up John's massive collection of jazz mags to bring them back to Earth,' said Gordon.
'We've asked him to open the windows and air the place, and sort out the washing up, although we've warned her that there might be a faint smell of sweat and sperm for the first few days.'
