There's some probably sound advice that says never actually meet your heroes face-to-face because they will most likely disappoint in the flesh.
A corollary of that might be never let your anonymous heroes be unmasked ... because the mystique is gone.
So it was with a mixture of interest and disappointment that I read yesterday's revelation from the UK Daily Mail that they had identified — and put a name to — the legendary street artist hitherto known only as Banksy.
For more than 20 years this guerrilla art activist has daubed his work on walls and buildings around the world, and never been caught.
He has helped elevate graffitti — once a criminal offence — into high art worth hundreds of thousands of dollars, and the political and social comment implicit in his work has provoked a response wherever it has appeared.
