Juraj Kralik is a well-known Slovak artist who, at one point, worked on a project where the legendary Czechoslovak tennis player Martina Navratilova shot tennis balls covered in paint onto a canvas, creating various variations of colorful images. I collaborated on one such canvas and painted graffiti with the inscription „Wall,“ to which Martina added her part in the USA using a tennis racket. The painting was also exhibited in a gallery in France – Tenniseum –Le Musée de Roland Garros
