I have a friend who lives in Vancouver that owns a vintage photo of "Portrait of the Eternal" and it is indeed a beautiful and transcendent image. When my friend received it in the post (he bought it from a gallery in London that was selling Bravo's work) it had a small crease in it. So he washed it in his archival print washer to swell the emulsion and get the crease out. It worked except all the spotting had been washed out so my friend had to spot an original Bravo print! Luckily my friend is an amazing printer and spotter and he said it was an honour to spot that print.
