PROBLEM: Verify if the sentiment of the following document towards the entity Myatt is Positive .  Mr. Myatt  now gives lectures on art forgery alongside officers from Scotland Yard. At  his  London exhibit   he  sold everything  he  displayed -- 68 fake Miros  Picassos  Giacomettis and the like -- at prices from $875 to more than $8 000. (The cheapest picture was a  Myatt  original  titled "Ceci N'est Pas Une Magritte.") Besides the Van Gogh  Mr. Myatt's house is chock-full of other fake great works -- Matisses  Ben Nicholsons  Braques. His studio is filled with half-finished Monets. Now 60  trim  with thinning gray hair and a very dry sense of humor  he talks forthrightly  but with a residue of shellshock  about his life of crime.

yes
