Ferlin had a minor career as an actor and debuted at the age of seventeen in Salomé by Oscar Wilde. He continued his career with a traveling theater company.
Although many of Ferlin's poems are melancholic, they are not without humor. Several were set to music and became popular songs such as En valsmelodi, an attack on the music industry. Ferlin sold over 300,000 volumes of his poetry during his lifetime. His lasting appeal is partly attributed to his vivid portrayal of central Stockholm before urban renewal and his association with the popular culture that flourished there then.
Även i Barfotabarn skriver N Ferlin om fattigdom, dagdriveri och hur nära döden vi alltid är. Lättlästa dikter som går rakt in i hjärtat, för det går att se sig själv i dem när dagarna är grå!
Citat frn några dikter: ” Tre bubblor brann till i Ginungagap: Frihet, Jämlikhet, Broderskap” ” Nu är det inte långt mellan människornas hus, men långt emellan hjärta och hjärta” ” Sen är det inte någonting du slumrar grönt och fagert och glömmer alla bittra sting och sår som livet gav”
