What is a word for someone who appreciates vintage items because of the history behind them? For example: someone who enjoys listening to records and wonders who in a past life listened to it, what they were doing when listening to it, etc.
A word that works for the questioner's purpose is antiquarian. The Webster's definition is just the bare-bones "somebody who studies antiquities", but the Wikipedia entry goes a little farther and says "aficionado or student of antiquities or things of the past."
The first paragraph of this article on antiquarianism by urban historian Roey Sweet is also of some interest here.
