This was the 1980 Battlestar Galactica annual - different from the film based book/annual from the same time. I'm honestly not sure if there were many more annuals of this type; as fans know Battlestar Galactica had a lot of money chucked at it and then hit difficulties pretty quickly, even the filming was chaotic by all accounts.
The annual is pretty typical of its type for the time, "authorised" published by Grandreams in London but actually made in Holland (others of the time were made in Italy). The book is in good enough condition (a bit "icky" due to eBay's quality listings, but I'd have this as "good" rather than the lowest "acceptable") and I'd imagine some might find the art interesting in some of the comic strips (hence extra photograph) as some I'm sure were working in comic strips at the time. Of course no writers/artists are listed so you can't be sure who unless you're an afficiando and recognise someones work.
Post or collect, but please do look at the other annuals I'm selling as you may well find others you'd like which might make collecting more worthwhile. I'll put a guide price for posting but that can be negotiated if necessary (finding "recorded delivery" costs a lot more and getting rather confused with it all!).
