Father knows best. “That’s what heirlooms are made of…the marks of use and love, inscriptions of wear, reminders that we were in the world together," explains @thaddeusoneil, pictured here with his son Cassius. "I personalized an ID bracelet with a quote from the great Long Island poet Walt Whitman that is dear to my heart and thinking. Also, an inverted female symbol which is both my initials and the most ancient iconograph for the earth."
