The database includes over 500 images, accompanied by information on location, subject matter, and technical features (where relevant). These images are mainly slides taken by or for Peter Rockwell in 1980s. They do not represent a systematic photographic record of the entire column, or even of part of the column; rather they illustrate interesting features of sculptural design or technique. Accordingly, a majority of the images are details, but there are some larger views as well.
