I Got Up At…, 1974–75: On Kawara’s works, particularly those associated with early Conceptual art, are exemplary of an oeuvre that is at once personal and universal. The confessional autobiographical quality of I Got Up At…, a series of postcards providing diurnal accounts of his rising times that he sent to his artist friend John Baldessari over the course of three months, document Kawara’s existence in time while also allowing that which is typically immaterial to assume material form.
