There’s a green and a grey version with each one of the famous Loesje quotes.
Loesje (/ˈluːʃə/; Dutch: [ˈluʃə]) is an international free speech organisation started in Arnhem (Netherlands) in 1983 and went international in 1989. Its charter is to spread creativity, positive criticism, ideas, philosophical ponderings and thoughts on current events by way of short slogans on posters. The posters are signed by Loesje, which is a Dutch female name, representing “a world wide collective of people who want to make the world a more positive creative place”. – Wikipedia
In addition, Hogeschool van Amsterdam wrote an article about the bicycle and myself.
