I was one of them. We were asked to send them with a positive message to the Arts centre of Worcester. So birds from all over the world were send by post. More than 300 postcards did arrive and were turned into a nice installation. (Still traveling around the world)
Recently they also made a book with bird postcards of the project: Open Hearts Open Borders. They selected 50 birds. Also my bird :-):
My postcard was a bit damaged during her flight. Such a great metaphore ... I just LOVE this project. All royalties of the book will be shared by Amnesty International and IBBY (The International Board on Books forYoung People)
If you wanna support this project, you can buy the book here.
Help Make this Book Fly! Thank you!!!
If you wish, you can read an article in the Guardian about the book here
