In this case, the names of some of the technical people will be known

Conservators, preparators, and installers usually work anonymously. Museum wall panels and catalogues seldom mention the names of the people whose work made the displays possible. Therefore, it was good to read in  The New York Times article about the installation of Picasso’s “Le Tricorne” stage curtain in the New York Historical Society building (“Picasso’s Stage Curtain Is Unfurled At New Home in a Precise Operation”, by Annie Correal, May 18, 2015), that  lead installer Tom Zoufaly and the rest of the crew signed their names to the wooden slat that holds the curtain to the wall alongside the signature of James Lebron —the man who installed the curtain in its former home at the Four Seasons Restaurant in 1959.
