Hey all - thanks for your responses, really appreciate them.
Here are some photos. I haven't got any of the interior pages as it's all still wrapped in plastic, but here's the cover and the front page (as well as showing the bits where the wrapping is loose).
I's love to know more anoint this if anyone has any info. I know these were given to licensees, but don't know if this is a global one or just UK (where I am and the show was obv. made).
It seems like a cool little item, but one that a bigger Muppet fan than me would probably get more out of.
