Back in 2014, Network issued a Supermarionation box set that included DVDs, Blu-Rays, cards... and a special issue of TV21 continuing from where the first series left off in 1969. A full tabloid-sized 24 page edition designed by editor Martin Cater to look like the TV21 comics of the period.
It was an expensive box set, and you couldn't buy the comic separately, but now you can! Priced at just £1.25, copies are available from The Official Gerry Anderson Store at this link:
Admittedly if you want the "free gift" you have to buy that separately but at least you have that choice:
I was one of the contributing artists/writers, producing a brand new Zoony the Lazoon strip for the comic. Other contributors included John Freeman, Mike Collins, John Burns, Brian Williamson. Paul McCaffrey, Gerry Embleton, Martin Asbury and more!
I'm sure this offer won't run forever so rush over to the Gerry Anderson Store to grab your edition now!
