Since the tracks are the same as any other PG Zep album (I assume so it doesn't mention any changes), the music inside the cover is inconsequential and you are essentially purchasing a one of art work, e.g. the cover. Pop art fluctuates in value so much that no one could predict it's value in the future, so one assumes the profit taking is now, thus not a good investment by any stretch. And then there's that high shipping charge....
