Evangelos Kotsioris

In our latest online edition of MoMA’s ArtSpeaks program, a member of our staff shares personal impressions of an artwork in the galleries. Here, Evangelos Kotsioris, curatorial assistant in the Department of Architecture and Design, looks at a section of the curtain-wall facade of the UN Secretariat Building, noting its innovations, imperfections, and the effects of 60-plus years of weather, grit, and grime.

Explore our collection work by work as we release a new video each Friday.
