Stylised illustration of a tea stall at dusk, deep blue sky and a hanging lantern glowing above the counter. At the centre of the counter sits a large kitchen scale holding a tea packet labelled 250 g, its display reading 300 g. On the left a woman in slate blue holds a rubber stamp over a sheet showing five identical stamped marks in a tight cluster, all off to one side of a printed target. On the right a man in saffron holds up a brass compass, its needle pointing at the target's centre. A wooden feedback box with a slot sits at the counter's edge.
