Deletion of Untitled (1967 Judd sculpture)

Comment: In addition to being in a museum collection and singled out as a "highlight", I've found a few sources that deal with this work in more than just passing. It seems that this work is important within conservation discussions and around ideas of original and copies in prefabricated artworks. "Do conservators dream of electric sheep? Replicas and replication", Louise Lawson (''Studies in Conservation'' Volume 61, 2016), "Nothing but the Real Thing: Considerations on Copies, Remakes and Replicas in Modern Art", Lydia Beerkens (''Tate Online Research Journal'', Inherent Vice: The Replica and its Implications in Modern Sculpture Workshop, Tate Modern, 18–19 October 2007), and "Corrosion Intercept tent packing and handling system for Donald Judd’s brass and copper sculptures", Eleonora Nagy (''Objects Specialty Group Postprints'', Volume Six, 1999) all deal with this work in some detail. The article can be expanded with a discussion of conservation and considerations of what is an original, per those sources. As well, the book ''Furniture, Structure, Infrastructure: Making and Using the Urban Environment'', Nigel Bertram (2013) mentions this piece. A couple of points: I don't believe that ''every'' work by a major artist should have an article and untitled works such as this are extremely difficult to find good sources on. I think in this case, however, a number of useful sources dealing with the work itself beyond a passing mention, and addressing topics that help expand the article, go a long way to establishing notability and satisfying  concerns
