The basis for the work Indicators is a small black box with
the label 'Indikatorenpapiere mit Farbumschlagtafel' (Indicatorpaper
with table for the change of colours) and the logo of the
company Bayer. When Böhm buys this box at the fleamarket
it contains a list of the indicators and the table (see below).
All twelve missing indicators are replaced by Böhm in cooperation
with Debby Rebsch. Different material from various sources,
fitting the colours are laminated and correctly labeled.
The work was given to Alexandra 'Nana' Bruns in 2001 and
is in private property since then.
