The majority of art and collectibles forgers aren’t trying to fool museum curators and auction house experts. They’re trying to find buyers ignorant and gullible enough to fall for their scams and fakes that that museum curators, auction house objects and seasoned collectors would identify in two seconds.
And most people who buy what are obvious fakes to experts think they are getting a steal from the seller. They think the ignorance-pretending scammers are the rubes who don’t realize what the have on their hands and are offering for so much under market value. Forgery sales regularly involve greed and deceit from both parties.
