Raymond Pettibon (born June 16, 1957) is an American artist who lives and works in Venice Beach, California. Pettibon earned an economics degree from UCLA and worked as a mathematics teacher for a short period, before completing his BFA in 1977. Known for his comic-like drawings with disturbing, ironic or ambiguous text, Pettibon's subject matter is sometimes violent and anti-authoritarian. From the late 1970s through the mid-1980s, he was closely associated with the punk rock band Black Flag and the record label SST Records, these were founded by his older brother Greg Ginn. In the mid 1980s, he became a well known figure in the contemporary art scene. Pettibon works mostly with Indian ink on paper and many of his early drawings are black and white. He often introduces colour through the use of pencil, watercolor, collage, gouache or acrylic paint. Pettibon started working in collage in the mid 80's with simple newsprint collaged onto black and white images. In addition to his work in black and white on paper, Pettibon has also made animations from his drawings, live action films from his own scripts, unique artist’s books, magazines, prints, and large permanent wall drawings. With most of Pettibon’s work being in black and white, it makes them quite distinctive and original. Also the way in which he draws makes his work memorable, they are pretty detailed and different to other artists. His work cannot really be compared to the other artsits I’ve chosen, his style is very inimitable and unique.

Frank Shepard Fairey (born February 15, 1970) is an American contemporary graphic designer and illustrator who made his fame through the skateboarding business and his work is very different to that of Raymond Pettibon. In 1988, he graduated from Idyllwild Arts Academy, and in 1992 graduated from Rhode Island School of Design with a Bachelor of Fine Arts in Illustration. He first became known for his "André the Giant Has a Posse" OBEY sticker campaign. His work became more widely known in the 2008 U.S. presidential election, specifically his Barack Obama "Hope" poster. He created a series of posters supporting Barack Obama's 2008 candidacy for President of the United States and became even more popular when Obama went on to win the election. Fairey’s art, which has its roots in the skateboarding and punk rock scenes of the 1980s and early 1990s, fits easily into anti-authoritarian and freedom of idea. Fairey has been arrested several times for vandalism, like most street artists, Fairey considers this as honourable for what they believe in as they are making a point to the world around them. At first, Fairey considered the “André the Giant has a posse” stickers as just a joke and nothing serious, but as the stickers began multiply and as people began buzzing about what they meant and who was behind them, his attitude began to change. What started as a joke became a way to get people to question their surroundings. In particular, Fairey took aim at the consumerist messages in ads, billboards and other form of mass media. Since then, the André the Giant image has become Fairey’s signature image, appearing on everything from his fine-art prints and paintings to a line of commercially licensed skateboards and street clothes. Most of his work consits of very bright colours, mostly blue, red and yellow. This makes his work as much as distinctive as Pattibon’s but in a very different way. They are easy recognisable and there are examples of his artwork all over the world they are that famous. They are contrasting in artwork as Pettibon’s is black and white and Fairey uses bright bold colours. You could say that Fairey has better technique as the use of the colours makes his work much more memorable and it sticks with you longer.

Boleslav Felix Robert Sienkiewicz (born May 3, 1958) is an Eisner Award-winning American artist and writer best known for his comic book work, for Marvel Comics' The New Mutants and Elektra: Assassin. Sienkiewicz often utilizes oil painting, collage and mimeograph. Sieniewicz attended the Newark School of Fine and Industrial Arts in Newark, New Jersey. After art school, he showed a portfolio of his work to DC Comics' art director Vince Colletta, which led to his breaking into the field at age 19. His art style was heavily influenced by Neal Adams. His work for Elektra: Assassin is very good and detailed and similar in style to Fairey. There is  similar style and colour themes in his work as Fairey, the colours stand out in the comics and catch the eye. Elektra, the character is dressed in red making her stand out more than any of the other characters in the comic. His work is quite sketchy and much less defined than that of Fairey’s work, however his line drawings and sketches are similar to that of Pettibon.
