This book originally was supposed to be the periodical Neptune No.2 (Neptune No.1 is held by the Sackner Archive). The front cover is stencil cut with the word NERVOUS and the back cover is stencil cut with the word SYSTEM. The handwritten, obsessive text is concerned with the emotions. Kurt Allerslev describes Nervous System in correspondence with Marvin Sackner that "the end result is a beautifully charged multiply printed edition of ten. Nervous System smells of ink and sweat sweet sour electricity. Lush dense compositions explore the interconnectedness of nerve form and letterform." -- Source of annotation: Marvin or Ruth Sackner.
