You find that with British f.o.h stills, sometimes they re-use the original stills, and even posters when the film is re-released, they are often altered by using snipes. This maybe a cast alteration, or in this case it may have listed Connery AS Bond and changed to IS because Connery wasn't the current Bond. like on a lot of YOLT posters... If you find an original and compare them you can soon find the alteration.
These are still considered First release, it's just they may have been used on 3 or 4 of the re-releases also...
Edit:- Didn't spot the enlargement feature, it looks as thought they have changed the credits to "Starring Sean Connery" instead of "Sean Connery is James Bond"...
