Popo from Lithonia, Georgia, conveys his gratitude to his mother for her selfless efforts through his works. In her graffiti, there is a moving painting. In her words, "The picture on the wall is my mother holding me in her arms as a baby (the real picture of my family). Below the picture, I will take care of her when she grows up in the future."
On Monday night, Jimmy Fallon announced Popo as the winner of the competition at The Tonight Show.
The National Graffiti Google Competition began in 2008. This year's finalists'works include magic kites, space travel, green environment, comic books, agriculture and the family love of Popo. Popo said she had been interested in art since she was 3 years old, but had "a huge artistic barrier" when she graduated from high school. Her work is to thank her mother.
"I had this idea at the last minute, actually before the deadline," she said. "I looked at the picture of my mother (the real version of the painting) and thought, 'Hey, why don't I exchange roles?
Popo's graffiti will be displayed on Google.com for a day, and she will receive a $30,000 university scholarship and a trip to Google's headquarters in Mountain View, California.
