Lik's Ghost is not doctored. It is the real thing.
The listing is a private buyer selling off at a profit in the UK. Peter Like is Australia-based though travels the world.
Lik's works do not command such astronomical prices. Here in Australia the highest paid for his work has been AUD$18,640 for a panorama of a settler's ruin in outback South Australia, printed to Ilfochrome Classic by ChromaColour (out of business).
