WALLS is part of ABCEUM, a multi-volume colloborative project produced by ABC [Artists’ Book Cooperative]. 

ABCEUM re-imagines the museum as a book installation. Each room in the museum is a print-on-demand artist’s book of a different size and material. Assembled, the 22 self-published books constitute a variable floor-plan which visitors can wander through. ABCEUM is an evolving project that can be added to and expanded, with its own changing programme of exhibitions—much like any museum. In ABCEUM, however, the idea of a museum itself can become its own subject.

WALLS is organised by Hermann Zschiegner.
A participatory project bringing together fifty artists that took photos of an empty wall in close proximity to a work of art they feel connected to.
