There is mention on Amazon of this TV21 book - here: "TV Century 21 Complete Dalek Strips In One Exciting Book Ultra Rare Proof Book".
It is described as:
"A fantastic 100 page Complete Dalek Comic Strips as they appeared in the TV Century 21 Comics of the 1960's. This book is one of the very few proofs that was made to be approved for a book release. Sadly, the book never went to print, hence the reason why it is so very very rare. Every comic strip that was produced for the comics, have been reproduced in this book, in full colour."
Now I know nothing about this proof book but the mention of TV21 drew me there. I'm not a big Dalek fan so I can't comment on its rarity. However, the publication in the pictures looks a lot like a report I might have done in my office, with a plastic cover and a plastic spine!
Does anyone know anything about it?
