Public art in Somerville has enlightened me in many ways in recent years. Here are two more examples, each enlivening my resources as a long-time volunteer guide at deCordova Sculpture Park and Museum in Lincoln. Both focus on fascinating aspects of Somerville’s Union Glass Company, owned by Julian deCordova through the early years of the twentieth century. One is among the seven vibrant panels of the Union Square History Murals on the building where Webster Avenue (55-50) and Prospect Street (70) intersect. The other is a bright sturdy signpost, among more than fifty others in Conway Park on Somerville Avenue. Here are photos, quotes, and notes to elaborate their connections.
