The Tapstone mark — five hand-drawn stones stacked and balanced.

Some objects hold a voice.

A Tapstone is an object with a story bound to it — a wooden disc, a signed canvas, a memorial. Hold a phone close and the story plays. There’s nothing to install.

A potter can press the mark into wet clay. A painter can brush it into the corner of a canvas. Wherever it appears, it means the same thing.

The stacked stones are how you recognize one. What is this mark?
