Among the photos on your walls, the art you’ve created, the things you’ve written or read – is there something you’d like to preserve for history? Something that you think deserves to be beheld by future generations, either for their edification or amusement?

An Austrian project is offering a means to accomplish this by way of burying clay tablets of your design into a salt mine. Memory of Mankind will etch words or photographs into clay. They produce two copies of each tablet. You get one and the other is buried inside Halstatt’s salt mine. If you’d like, your design can also be shared in the online version of the archive.
