I think "Andy Warhol" might be my favorite, but nearly anything from Hunky Dory or the Ziggy Stardust era is bitchen'.
Interestingly, Bowie is the wealthiest entertainer in Britain, surpassing even Paul McCartney, largely due to brilliant self-marketing and investments (e.g., he actually sold a release of public bonds a few years ago, backed by the royalties on his music). He is worth > $1 billion.
