Seagulls are painted on the side of a tour bus in Paris. Taylor Holland, professor of digital media at the Paris College of Art, has taken about 1,200 photos of tour buses over the last few years.
The first U.S. President, George Washington, was on one of the tour buses Holland photographed.
"I don't have any typography in my shots," Holland said. "I'm not really thinking about where the wheel is. I'm not thinking anything except where the graphic is in relation to the frame."
Holland rides his bike through the French capital, constantly searching for fresh designs.
"In an hour, I see 10 I haven't seen before," he said. "I see about 100 in any given outing. I never come up empty-handed."
