Someone who has the info. could you post or add the U.K. printings of the Freak Brothers series when you have time?
I know there were at least two publishers,
Knockabout (I have the light blue cover version of Freak Brothers #2 by them) and the Hassle Free Press printings (just won a .50p #1).
I have an extensive list of all printings (i.e., Freak Brothers, Fat Freddy's Cat and Fat Freddy's Comics and Stories), but it's going to have to wait for a while as I'm swamped with work and other things. There are between 12-14 printings of FB #1-5 and about half as many for later issues.
Hassle Free Press and Knockabout are the same thing. It was just a name change.
