SIZ or the Self-managed interest community is an association of authors who are approaching the art market collectively. Materialistically grounded in social reality, SIZ Gallery, has chosen to confront the problem of financing artistic practice on the ideal and practical level. Drawing from historical avant-garde, which has due to mostly ephemeral artistic practices experienced the dissolution of the concrete art object that can be marketed (to which the art market has continuously adapted) SIZ considers the economical exchange of artistic goods and questions new social frames that grow from modified economical models.
