What starts out as a simple question -- where is it? -- becomes an obsession. The mysterious origins of a Windows desktop image, by Nick Tosches: vanity fair
Also by Tosches and worth tracking down is his biography of Dean Martin -- Dino: Living High in the Dirty Business of Dreams. Tosches chronicles Dean Martin's life and the writing takes on a semi-hallucinatory darkness as Dino reaches old age, closes the curtains, knocks back some more pills, and opens another bottle.
Living High in the Dirty Business of Dreams is out of print but available at places like the 'new, used, rare and out of print' retailer: abebooks
