I would have to say, books, posters, my book of lyrics, quotes, poetry, etc, unusual / mediaeval clothes, random furs, skeletons, paperwork, etc...

I remember when I was in high school, I was given an opportunity to do a display that was to incorporate stuff that I felt symbolised me - things from my room, that would give my fellow students a look at a person from their things, without their name... I put in lots of colourful, bright things, silk, ribbons, flowers, books, poetry, stuffed lizard, my dagger, my Bible open to Psalm 8, rocks, shells, etc... I got many very surprised reactions when people realised it was mine, because I hung with the crowd that was considered 'Goth', wore a fair amount of black, and was 'scary'... people realised then that they had no idea who I really was.

Funny, my friends weren't surprised in the least.
