Precarious Balances Series of Drawing
In the 80s , Zeigler produced a large body of prints and drawings under the title of Precarious Balances Series. This series explored issues related to nature and culture, and the vital importance of understanding interrelationships among natural as well as social and political phenomena. Photo collages and drawings were employed in developing images that were then developed as large-scale drawings on paper and Mylar, as well as in prints in the media of etching, lithography, and screen printing.
