RedBall Project is a public travelling street art piece by US-born artist Kurt Perschke.^[1][2][3] Considered “the world's longest-running street art work"^[4][5][6] the project consists of a 15 ft inflated red ball wedged in different city spaces in various cities around the world.^[7][8] Placed in a choreographed suite of installations within a city and usually lasting one or two weeks, each specific site lasts only one day.^[9][10] RedBall Project has received strong international media and public attention,^[11][12][10] and has been featured in several urban art books, art journals,^[13] and media.^{[14][15][16][17][18][19][20][21]}

RedBall was created in 2001 by contemporary artist Kurt Perschke.^[22][23] Perschke is best known for his works in sculpture, video, collage, set design and public space.^[24][25] Other prominent works by Perschke include commissions for various institutions including The Contemporary Art Museum in St. Louis, Barcelona Museum of Contemporary Art, and Technisches Museum Wien.^[26] His set designs for Kate Weare Dance Company have also received critical accolades in The New York Times.^[27] Born in Chicago, Perschke currently lives and works in Brooklyn, New York.^[28][29]

The RedBall is 15 feet in diameter (4.5 meters) and weighs 269 pounds (122 kg) inflated or 250 pounds (110 kg) deflated.

In May 2013, Perschke filed a lawsuit against the European conglomerate Edenred, S.A. over the use of RedBall Project’s concept in a promotional campaign. The international law firm Gibson, Dunn & Crutcher took on the cross-border dispute and filed a complaint in Federal court against Edenred.^[35] The case was settled out of court. While the precise terms of the resolution remain confidential by mutual agreement, it has been reported as “a legal victory for RedBall Project”.^[36] Perschke said that he views the resolution as favorable because it was based on terms that respect his intellectual property rights.^[37][38] In 2015, Perschke accused Shell Oil Company to have used his concept of the RedBall project in a global print ad campaign.^[39] The accusation on artistic copyright infringement received media attention.^[40][1] The ad campaign was ended, and the case was settled out of court.
