Remarkable, but not a completely unprecedented forger's trick (#122555)

A fascinating and rather depressing tale. Allen, however, is not the first to have pulled this trick on the British public records. John Payne Collier, the noted 19th century forger of Shakespeareana, inserted one of his bogus creations into a document bundle at the State Paper Office (later the PRO).


Mais ledit précédent reste unique et isolé. 29 faux introduits en 5 ans (de 1999 à 2004), c'est inouï et presque inconcevable !
