The Organization for Security and Co-operation in Europe (OSCE) is, according to Wikipedia, “the world’s largest security-oriented intergovernmental organization with observer status at the United Nations”. Its 57 participating nations address “a wide range of security-related concerns, including arms control, confidence- and security-building measures, human rights, national minorities, democratization, policing strategies, counter-terrorism and economic and environmental activities.”
The OSCE website pairs Merriweather with Open Sans, which is used in its regular and condensed widths. The organization’s all lowercase logo is based on Palatino. Designers for both logo and website are unknown.
