Kosti Ruohomaa took a series of photos illustrating the connections between the people living in Calais, Maine, and St. Stephen, New Brunswick, just across the border in Canada. Kosti included images of the institutions that serve both communities like the Chipman Hospital in St. Stephen and the Calais Free Library. He also traced relationships, such as a Rotary Club or couples with members from each side of the border.

Four photos  from this series, which he titled “Hands Across the Border”, were published in the Saturday Evening Post on August 31, 1946, alongside an article written by J.C. Furnas with the title “St. Calaisphen, North America” pp 16-17.
