The Free On-line Dictionary of Computing (30 December 2018):

wallpaper

   1. A file containing a listing (e.g. assembly listing) or a
   transcript, especially a file containing a transcript of all
   or part of a login session.  (The idea was that the paper for
   such listings was essentially good only for wallpaper, as
   evidenced at Stanford, where it was used to cover windows).

   The term is now rare, especially since other systems have
   developed other terms for it (e.g. PHOTO on TWENEX).
   However, the Unix world doesn't have an equivalent term, so
   perhaps wallpaper will take hold there.  The term probably
   originated on ITS, where the commands to begin and end
   transcript files were ":WALBEG" and ":WALEND", with default
   file "WALL PAPER" (the space was a path delimiter).

   2. The background pattern used on graphical workstations under
   the Microsoft Windows graphical user interface to
   MS-DOS.
