Cracked lithography stone marked with numerical annotation, part of Plattenkalk series.
A lithography stone, exhibiting a distinct vertical crack along its right side, is captured in a black and white photograph. The stone, a subject in David Christensen's 'Plattenkalk' series from 2026, features handwritten numerical notation "+ 0.70" and a downward arrow in its lower left area. The image emphasizes the material's texture and damage, set against a dark, undefined background.
