The work glass box that includes on its back surface the text of a sandblasted reproduced letter from Frederic Chopin to a friend regarding his landlord's negative reaction to the learning of Chopin's having contracted tuberculosis, a metaphor for the often negative contemporaneous reaction to AIDS. The red colored salt crystals & the vellum along the bottom & the diagonally upright plexiglas rod placed in the box symbolize splitting (spiting) of blood from the tuberculous lungs. -- Source of annotation: Marvin or Ruth Sackner.
