George Underwood didn't always wanted to be an artist. In 1963 he joined the Beckenham School of Art and became more interested in music rather than visual art. He even made a record called 'The King Bees.' But soon after, George Underwood went back to school for art.
He then found himself working as a illustrator. If you think his art resembles that of classic book covers, then you are right since he specializes in fantasy and horror book covers. Underwood then moved on to oil painting and mixed themes of fantasy and realism. I encourage you to have a look at his portfolio and his art. The paintings are spectacular.
