Boston Tapestry by Alfred M. Duca located in the lobby of the prudential tower. The theme of this major work is Boston ? an interwoven abstract pattern of its people, its history, its topography, its presence. Here are its people, its ships, and its spires. Here are its hills, its trees, its symbols, ethnic and religious. Wings, sands, and waves are woven into the rolling patterns of this tapestry.
