As an anthropologist Ellen Hoefnagel has always been fascinated by children's' perspectives of their surroundings. Inviting environments stimulate children, and good design supports this. For over twenty years she has been collecting children’s and teen’s vintage designs sourced on regular trips to Paris and Amsterdam. Since 2014, Hoefnagel has sold her collection online. Though the collection largely focuses on children's design, there are also some adult design classics to be found here too.
