Roy Lichtenstein, truly one of the coolest artists of the 20th century (he died in 1997 *sniff*), painted hundreds of wonderfully retro-style works during his lifetime. He, along with Andy Warhol, made pop art legendary.
Recently one of his paintings (titled “Ohhh ... Alright”) sold in New York for the record sum of $42.6 million (£26.4 million). The person that bought the painting was an anonymous telephone bidder and I am literally aching to know who it was! Imagine being able to spend that kind of money on such a classic piece of 20th century history. Whoever it was, I'll bet that painting looks friggin' amazing up on their wall.
