As far as self-portraits go, ‘Seascape: Floating Costume to Drift for Eternity I (Armani Suit)’ by Ashley Bickerton is a little on the dark side, despite its bright orange buoys. Made in 1991, just two years before this regular on the downtown New York art scene relocated permanently to Bali, it seems to foretell his departure. Quixotic, a little lonesome, and stylishly branded by Armani and his signature ‘Susie’ logo – a semi-corporate brand of his own invention – Bickerton’s craft signals a dignified leave-taking, a memorial to a past life and an adventure about to begin.
