A project from Estonia, a “blog of postcards for world peace”:http://postcardworldpeace.blogspot.com. From the site:
bq. The idea is simple: Send us a postcard from your country/city (or any postcard you want) writing in the backside a message of peace to the World. All the postcards will be uploaded in the blog, and there will be a record of how many postcards per country we receive (including a map showing the coverage).
