Snapshots of more than 40 years of international volunteer efforts are now on display at Incheon International Airport.

The U.S. Embassy in Seoul and the Korea International Cooperation Agency kicked off a two-week photo exhibition on Monday, shedding light on overseas volunteer missions by Americans and Koreans over the past four decades.

Photos taken by the U.S. Peace Corps in Korea between 1966 and 1981 are being showcased along with those of Korean volunteers in developing countries from 1991. Organizers say they plan to expand the exhibition to 14 cities throughout the country.
