I suppose that what EW said is the most obvious link. I'm pretty sure that if you'd put a few records in the showcase along with some books, e.g. Rime of the Ancien Mariner and Lord of the Flies, together with a book on Alexander the Great, that will make quite a few people wonder how that all ties together. I would probably center everything around some interesting, eye-catching work of art that doesn't directly refer to any Maiden song, but does serve to illustrate or illuminate a certain thing that either forms a long standing idea in their music, or that reflects my feelings for the music.
If you want to, I can give that timeline I posted ages ago an overhaul to make it more appealing. I remember it was okay, but not as good as it could or should have been.
