The music world lost another of its memorable stars on Sunday as George Michael died at age 53.
He sold more than 100 million albums during his career as a solo artist and as half of the band Wham!, which arrived with the first of its three Platinum albums in 1983. His debut solo album, Faith, has sold more than 25 million copies since 1987.
But when it comes to cardboard? Well, collectors really only have two places to look.
