So, the middle circle is from the top, clockwise:
For The Greater Good Of God (Wolf in clothing, blood around homes, cross)
2 Minutes To Midnight (Baby in the womb, nuclear head)
Revelations (Eyes of the Nile are opening = crocodile eye, the 6es also somewhat resemble a black abyss)
Ghost Of The Navigator (Rum/Whiskey, a pair of compasses and a ship wheel)
Number Of The Beast (The goat in the middle)
Looking closely at the last one: I think it's a star/sun surrounded with 6 snowflakes. So I don't know what could this be. But I think it's either FOTD/SOL or SIASL
The far right window:
Alexander The Great (Mosquito)
The Clansman (Scottish Flag)
Flight Of Icarus (Self explanatory)
The right window:
Trooper (everything, with a Powerslave sphinx thrown on the top for good measure)
The left window:
Brighter Than A Thousand Suns (The nuclear mushroom)
Flash Of The Blade/Sun And Steel (The blacksmith)
The far left window:
Flight Of Icarus again (man with wings)
Moonchild (seven deadly sins...)
So putting those in somewhat logical order:
Moonchild
Ghost Of The Navigator
Revelations
Brighter Than A Thousand Suns
The Trooper
The Clansman
Flash Of The Blade/Sun And Steel
For The Greater Good Of God
Stranger In A Strange Land
Alexander The Great
Fear Of The Dark
Iron Maiden

The Number Of The Beast
2 Minutes To Midnight
Flight Of Icarus (Bruce used to close with it on solo tours)
That, my friends, is an amazing set.
