Here's what I'm reading from the tour poster:
Revelations (cathedral), Aces High (spitfire), Trooper (Eddie 1), Senjutsu (Eddie 2), Two Minutes to Midnight (mushroom cloud), Flight of Icarus (Icarus), Where Eagles Dare (eagle), Writing on the Wall (motorbikes), Fear of the Dark (lantern). Guess the figure on the origami horse points to Stratego. Not sure what to make of the pit in the middle. If we're going by a reference to "hell" we only have about a good dozen of Maiden songs to pick from. None of the poses of the figures or the hand gestures seem to point to anything specific.
