At 34cm X 25cm this is one of the larger pieces I completed for GW in the late 80s, (too big to scan in one go!)
Set at the time of the Horus Heresy....I don't remember the backstory but there are some odd characters mixed in with the loyalist marines: An Imperial Guard commisar and an odd scientist guy. You tell me what's going on!! I'll add this to the illos for sale and if I can still make it I'll bring it to Oldhammer Day at the end of August.
