I found a painted stone. Now what?
Look at the back of the stone. There should be the information to read where you can report the find. This can be a website, a Facebook group, an Instagram account or even completely different possibilities. In any case you should use one of the possibilities to report the find to the artist, because that’s what he/she is waiting for.
My stone has no contact information or they have been lost.
In this case, there are various Facebook groups that pick up such stones and try to bring them “home”. An example is the group Heimatlose Steine ohne Gruppe (Muscheln & Holz sind auch ok ??). (Sorry, german group)
