The thing that boggles my mind is that price – or even a tenth that price – for what is basically an illustration, a book cover. Who the hell pays $5.7M for a random SF illustration like that? There are probably tens of thousands of better quality works floating around for $57,000 or less. Just go to any major SF con art show.
Of course it’s just my opinion: I’d say the original is dull and weakly composed but it’s not awful; however the Brown version seems to me to be garish and ugly.
