Saw this on ebay. Its called best of plug im not sure what it is my guess is that it's the pullout sections from the Beezer and Plug but im not sure also the date given is 1977 which is whilst the Plug comic was still ongoing and had yet to merge.

They'd actually be from 1979-80, and yes, they're from the Beezer.
