There is this tradition on Pardubice summer camp, that the winning children team gets t-shirts as a main price. T-shirts have a logo and color based on the theme of the year. In the year 2007 the theme was "Around the wold" and my logo design was used.
The original design was similar to what you can see on the picture, but instead of a plane a balloon was floating over the Earth. But our approach to the theme was from more modern perspective, thus we replaced ballon with a plane.
