This paper examines changing gravestone design in Prince Edward Island (PEI) (1820–2005) and relates these changes to changing modes of production in the monument industry. Information from field surveys, newspaper advertisements and business correspondence reveals how supply-side factors helped shape the morphogenesis of the island's cemetery landscapes. Among these, different sources of raw materials and manufacturing innovations over time resulted in the use of harder, more durable types of stone. With these changes, gravestone production and design moved increasingly away from local monument works towards off-island producers in Vermont, New Brunswick and Nova Scotia. Since the early 20th century, PEI's gravestone suppliers vertically integrated along Fordist mass-production lines and increased choices available to local monument sellers and their consumers.
