By pledging $90, you get to own a letter. This is how it works.
After we have completed the project, we will have a extensive database of all the letters from A-Z. There will likely be hundreds (dare we say thousands?) of letters from all over the world, many of them repeating.
You will then be able to pick a letter of your choice (e.g. "an A in Berlin", or a "K in Salt Lake City"). Along with the letter, we would invite you to send us a short text that would be written into the metadata of the letter image. An example could be, "G: For all the geographers out there".
Since in the end, the dataset will go "public" or be "opensourced", we would let you decide if you would like it to be excluded from the opensource dataset or included. If it is excluded, that letter is yours and will not be available to the others. If not, there is the chance that the letter you chose can be incorporated into other projects. This could be interesting in a way, because then your letter and your short text might "live on" through those other projects.
We hope this is understandable and agreeable. Thanks so much for your support and being an integral part of making this happen!
