Some years ago, I found what appeared to be a partial logo for the Illyrian Palatinate's mercenary force - variably called the Arms of Thor or Thor's Army (Right Arm of Thor & Left Arm of Thor) in some black and white art in an official BattleTech product. The problem is, I can't currently locate the original source.
The illustration, as best I can recall, shows a female backed up against a 'Mech limb, with the "Thor" logo partially obliterated by incoming fire. She's looking to the viewer's right (to her left) and shooting that direction, and there's incoming fire from off page from the right, hitting all around her.
The reconstructed logo is attached. If anyone can help me identify the source, that would be grand.
