projecting signboard; side signboard
A signboard that extends outward from a building, often perpendicular to the wall, commonly seen on traditional shopfronts. Contrasts with 袖看板 (sodekanban), a similar projecting sign.

A wooden projecting signboard was displayed in front of the long-established shop.
On this street, each shop puts out a colorful projecting signboard.
Both refer to projecting signboards, but 袖看板 is a more general term for a sign attached to the side of a building, while 突き出し看板 emphasizes the action of protruding outward.
Compound of 突き出し (tsukidashi, 'projecting') + 看板 (kanban, 'signboard').
