Also it should be said that they are not "annuals", as several seem to come out a year. And not always at the same time of year. There has now also been a "Valentine Picture Library" book for the girls, all based on 50's/early 60's love songs from famous "dishes" like Cliff Richard. This one is not blown up, though, it's the same size as it would have been originally published in.
I read somewhere that another Battle Picture Library* one is coming out sometime this year, but i can't remember where, or what it will be called.
*-Battle Picture Library came before Battle, the comic with Charleys War etc in. Though i beleive after this was started Battle Picture Library came back, but with a similar title to the weekly comic though it was mainly re-prints of the old stories... but don't quote me on that.
