Having collaborated between 1998 and 2006 as Artlab, not only as makers of paintings, drawings, sculptures, and installations but as presenters of the work of others, Charlotte Cullinan and Jeanine Richards began operating less anonymously as Cullinan + Richards in 2006. A book they published that year, which marked the transition by featuring both monikers on the cover, was inexplicably dated 1921–2006. Why 1921? A few of the more recent works documented in the book have titles or subtitles citing that year, but the event to which those paintings and sculptures referred remained inscrutable.
