The most daring of Bonnard's self portraits make it clear that they are mirrored representations. In most of these late works the subject is transparently Bonnard's own mortality, and in two works, this is metaphorically expressed by the wartime blackout curtain depicted next to the artist's image. They are among the most poignant self-representations in Western art: querulous apparitions, despairing, frightened, self effacing. Bonnard died in January 1947. Some 15 months later, in May 1948, MoMA opened its first retrospective exhibition of his work; a second was held in 1964. This third Bonnard retrospective at the Museum celebrated a career that ended more than half a century ago but remains as vital and challenging as any in contemporary art.
