It has a number 9 stamped in red on inside cover. I've been on the Post/Tel web site but can't find any information on there and haven't seen it for sale or mentioned anywhere.
Still can't find any details on this book, I can't be the only person who has one, any info appreciated.
It's been 5 months since you first posted this, I'd guess the other 8 owners of this album have not read this thread. Perhaps they all speak and read Chinese only. That is a very limited edition.
