Teacher: Now, understand the problem? Solve this instance: Image caption Andy Fields thinks the original owner hid the sketch for safekeeping 
  
 A collector who bought a batch of paintings in a US garage sale has found what is believed to be a sketch by pop artist Andy Warhol among them. 
  
 Businessman Andy Fields, 48, from Tiverton, Devon, paid $5 (£3) for the five paintings in Las Vegas in 2010. 
  
 When he decided to reframe one of the paintings he found the sketch hidden behind it. 
  
 He has been told by a valuer that the sketch could be worth £1.3m - but says he does not want to sell it. 
  
 'Very good bargains' 
  
 He told BBC News: "My friends and I go to garage sales. It's like car boot sales but in a garage and we were just travelling around Las Vegas. 
  
 I want to keep hold of it - I collect art - but I don't want to sell it for a few years Andy Fields 
  
 "It's always a fun thing to do, you find some very good bargains. 
  
 "This guy sold me some paintings for $5. 
  
 "I was reframing one of the pictures and took the backing off and saw a picture looking back at me and recognised the bright red lips of an Andy Warhol." 
  
 It is thought Warhol did the sketch of 1930s singer Rudy Vallee when he was aged nine or 10. 
  
 Mr Fields said: "The experts think it is of historical importance because Warhol did not do pop art properly until he was 23." 
  
 He thinks the original owner must have hidden the sketch for safekeeping. 
  
 He now hopes the sketch, drawn on tattered paper, can be put on show in a museum. 
  
 He said: "It's much better than putting it in a vault somewhere. 
  
 "I want to keep hold of it - I collect art - but I don't want to sell it for a few years." 
  
 Warhol's prints can fetch millions of pounds. 
  
 His first self-portrait, a four-panel acrylic silk-screen in blue hues, fetched $38.4m (£23.5m) in 2011. ||||| Andy Warhol sketch bought for $5 by British businessman at Las Vegas garage sale is valued at £1.3MILLION 
  
 A businessman claims he bought an Andy Warhol sketch worth £1.3million for just $5 at a garage sale - and only discovered it by chance. 
  
  
  
 Andy Fields, 48, said he purchased the work of art from a drug user whose aunt used to care for Warhol when he was a child. 
  
 The illustration - from the late 1930s - is believed to have been drawn by the artist when he was 10 or 11.

 Father-of-one Andy purchased a number of paintings by the author Gertrude Stein at the garage sale. 
  
 It was only when getting them framed that he discovered he had also bought one of Warhol's early works. 
  
 He says he had it valued at £1.3million - but it could theoretically fetch ten times as much if it was sold. 
  
 He has vowed to hang on to the piece and put it on display. The sketch shows Rudy Vallee who was an actor and singer in the 1930s. 
  
 Although the businessman, from Tiverton, Devon, claims to have had the artwork verified as genuine, doubts about it remain. 
  
 The piece it is signed 'Andy Warhol' and he only changed his name from Andrew Warhola in 1949. 
  
  
  
 Mr Fields, who bought it in 2010, said: 'I bought some sketches by Gertrude Stein at the garage sale and the Warhol work was actually behind one of these. 
  
 'When we were framing one of these I saw the Warhol work looking back at me there undiscovered. 
  
  
  
 'It's an incredibly important work. It redefines the works of one of the most famous artists of the last 100 years.

 Likeness? Rudy Vallee who Warhol sketched when he was aged 11 or 12 
  
 'It moves the birth of Pop Art back two decades, showing Warhol was already doing that sort of stuff at a far younger age.' 
  
 He claimed that several experts have verified the work as original. Mr Fields said he believes it is signed 'Warhol' rather than 'Warhola' because the artist only signed the work many years after he drew it. 
  
 'The way the experts have explained it is that Warhol never used to sign his early work,' Mr Fields added. 
  
 'When he gave work away many years later it is highly likely he would have been asked to sign it.. 
  
 He added: 'I am happy to be grilled by any expert in the world.' 
  
 Mr Fields said he wants the work to go on display in a gallery - and would turn down any offers to sell it. 
  
 Andy has also asked for an opinion on the paper on which the work is drawn and consulted Peter Bower, a forensic paper historian and analyst, who confirmed it was more than 60 years old. 
  
  
  
 Audrey Giles, a forensic handwriting and document examiner, was asked to assess whether the signature on the work was Warhol’s and concluded there were key elements of it which confirmed it was. 
  
  
  
 A 12ft painting Eight Elvises sold for $100million (£65m) in autumn 2008, in the biggest ever Andy Warhol sale. 
  
 His painting Soup Can (Tomato) sold for £5.6million two years ago - while Lemon Marilyn fetched £17.5million in 2007.

Student:
Andy Fields may inspire you to visit the local garage sale next time around. The British businessman and art collector says he bought a $2-million Andy Warhol painting for only $5 at a Las Vegas garage sale two years ago, the Daily Mail reports. In fact, he hardly noticed it until framing other pictures—then "recognized the bright red lips of an Andy Warhol," he tells the BBC. But the Mail says doubts remain about the authenticity of the painting—a portrait of 1930s actor Rudy Vallee—which Warhol allegedly painted at age 11 or 12. Why, for example, is it signed "Andy Warhol" when the painter only changed his name from Andrew Warhola in 1949? Because, says Fields, Warhol signed his early paintings later in life. And Fields claims several experts have verified the painting as original. Also, he prefers to have it hung in a gallery rather than sold for megabucks. The work "moves the birth of Pop Art back two decades," he says, "showing Warhol was already doing that sort of stuff at a far younger age."
