HÄPNA! - De Svenska Rekordåren, 2009
one collected magazine from each year 1954 - 1966

Sweden was never the center for production of science fiction.  But between 1954 and 1966 the sci-fi magazine HÄPNA! was published in Jönköping, Sweden.  In the history books of Sweden these years are called “de svenska rekordåren” (the Swedish record years).
