Okay, I didn't really understand what was going on with the guy with the fake beard. But, hey! I liked the science sign.
Frank Shepard Fairey produced the poster seen above as well as several of the more professionally produced posters I've shown earlier. Fairey "(born February 15, 1970) is an American contemporary street artist, graphic designer, activist, illustrator and founder of OBEY Clothing who emerged from the skateboarding scene. He first became known for his 'Andre the Giant Has a Posse' (…OBEY…) sticker campaign while attending the Rhode Island School of Design (RISD), which appropriated images from the comedic supermarket tabloid Weekly World News.
He became widely known during the 2008 U.S. presidential election for his Barack Obama 'Hope' poster. The Institute of Contemporary Art, Boston has described [him as] one the best known and most influential street artists. His work is included in the collections at The Smithsonian, the Los Angeles County Museum of Art, the Museum of Modern Art in New York City, the Museum of Contemporary Art San Diego, the National Portrait Gallery in Washington, D.C., the Virginia Museum of Fine Arts in Richmond, and the Victoria and Albert Museum in London." ~ Wikipedia
