Metro Litteratur is a recently launched campaign that helps to promote talented Danish authors, poets and graphic artists by distributing their works at various metro stations in the city of Copenhagen. The program is a collaboration between the Milan-based organization Subway Letteratura and the Copenhagen Metro Authority and is a result of a competition held earlier this year, which led to the publication of thirteen small booklets that are offered to passengers free of charge. writes. Every booklet is published in 300,000 copies and can be downloaded online too.
