Three finalists will present plans Jan. 19 for an Edgar Allen Poe memorial in Boston: Stefanie Rocknak of New York plans a statue of Poe with a trunk containing a raven, a heart, and pages of stories and poems; Ann Hirsch and Robert Olson suggest figures of Poe and a female who will represent his childhood trauma; and Jennifer Bonner and Christian Stayner want a triangular glass pavilion where Poe-related items will be on exhibit and for sale.
