Tomorrow Kings Appearances - Where?

I am fairly new to the amazing works of Ashley Wood and 3A. Buying up figures as fast as my budget will allow, but I’m struggling to understand where to find the stories behind these incredible characters, especially the Tomorrow Kings. I would be profoundly grateful if someone could direct me to the publications that contain TK storylines, such as the attached pic. Can someone please help? Thank you!

It's part of a poster which came folded in the TKLUB Number Six The Last Tomorrow King and the Archer box which was released back in June 2015.
Popbot #9 would be about Tomorrow Kings and is still in the works. So it's possible this artwork will be part of the storyline.

Q: Big fan of yours Popbot Universe, I want to know if you plan on wrapping it up in the near future and is Popbot 9 a last one? Also how is the film is coming along? Keep up the good work!

A: Pop 9 is a catch up issue, with a TK story, then 10 will be the start of the end! Film is like many films, waiting for the guys with money to hand it over, but as Im not gonna let POPBOT be something that strays from my vision, it takes a little more time get the backing!

Since most of this short story is out in the open and even Ashley posted it here on his Instagram ,I am not sure I have to enforce forum rule number 5 and ask you to remove your pic. So I won't.

This is the Archer, by the way.

lots of the early Tk story is in popbot vol 8, read that for starters. not lots of info on many of the newer Tk sans the short bit of info on sales image or box.

Also, here on the World of threeA Production Blog is more of the story (until it says: to be continued)

gar, thank you for the insights. Very sorry for breaking the rules....wont happen again.

Don't worry, no rules broken.
There's a thin line between what's allowed and what isn't.
If you posted scanned pages from a book it would be an issue.

Good luck with hunting down the Popbot stories.
It seems it always sells out almost immediately.
