Great book. A ton of memories of what it was like for us Brits waiting for Star Wars to be released over here in the UK.
Incudes release dates for London cinemas and general releases.
Also memorabilia that was released exclusive to the UK and behind the scenes of Palitoy and Marvel comics UK.
Magazine, tv shows and UK TV air dates and more.
Recommended.
