These were the young adult, paperback, versions of the films. I recently put The Black Hole version on from a few years before and they were still hardback then. I decided to put these three, now four (Return of the Jedi discovered recently), together as they're of a similar vein really, aimed at younger readers, part of the whole movie promoting (and reading promoting of course) package at the time.
The ET book was written by William Kotzwinkle and like the other is text and colour photographs from the film. The Indian Jones book is by Michael French while Dune is by Joan D Vinge. I doubt (can't remember!) if any diverge from the films that much. Return of the Jedi is also by Joan D Vinge.
Post or collect, but please look at the other books I have for sale as you might find it more beneficial to collect with others. If post, I've put what I have done in the past but we can negotiate on that if needs be.
Addendum: Apologies, but due to Royal Mail price rises I’ve, in turn, had to raise the post prices accordingly. Getting to the point where you genuinely wonder if it’s all worth it! I guess things can be negotiated here, but for me this is still the safest way to post.
