Good condition for age, I think. I'll say "ok" though just so no one expects something different to what i consider good for age. most pages have a slight dent in the bottom right where i've over zealously turned the pages, and there's a few small rips at the bottom of a few pages (pictured one of them, others are the same sort) All stickers are complete and in the book, they,ve been put in pretty well in most places, you can see which ones I struggled to find in packets, because I've put them in excitedly and missed the lines a little. It comes complete with the centre poster (completely stickered) as well as the original mail away leaflet to help complete the set.
I've included as many pics as Ebay would allow, so you can see the majority and how they look, and also see the few where I was so excited to complete a set I wasn't steady handed as they went in.
Overall, for a 34 year old sticker book for kids, I think its in pretty good nick and was something I proudly had next my SNES when I was hosting little tournaments in the school holidays, and later on sat next to my gaming collection. Now it's sadly found itself in storage, and I think it would be better enjoyed by someone else.
