mumok holds the archive of the art collector Wolfgang Hahn, head of the Museum Ludwig Cologne restoration workshops and founder member of the Gesellschaft für moderne Kunst in Cologne.
It contains contemporary documentary materials like invitations, flyers, and cards, all associated with the artists in the Hahn Collection (e.g. Daniel Spoerri, Nam June Paik, Marcel Broodthaers).
These include rare artistic items of great interest. At present we are working on a digital inventory of all the material.
