People collect many different things. They collect stamps, teddy bears, hats and other assorted items like buttons, that to many people simply do not make any sense to collect. However, there are also people out there who collect another type of item, and that item is used music memorabilia.
When they collect used music memorabilia, they are collecting things that have, for a time, been in the presence of musical greatness. They can be historical items like the album John Lennon signed for Mark David Chapman before he was shot, or it can be trivial and small like a scarf used by Steve Tyler in an Aerosmith show in Milwaukee in 1979.
No matter what the used music memorabilia is, it serves a useful purpose to the people who own it. For them, it is like touching music greatness and when they hold onto something like a signed Led Zeppelin IV, they are holding onto a piece of music history that puts them in touch with the rock gods who created it. For many, this is as close as they get to having a religious experience.
Music memorabilia is an amazing thing to have in your house. When you have a guitar signed by Jimmi Hendrix up in your den, people are going to ask you about it and envy you for it.
They will ask you where you got it, they will ask you how much it cost and they will always ask if the touch it.
