圆盾背面，两道皮革挽带固定在木板上

An original round wooden shield faces backward on a craft workbench. Show curved plank seams, rivets around a central iron boss, two worn leather arm straps and stitching. One old glove nearby gives scale. Low sidelight reveals wood grain and hammered metal. No heraldry, person, text or logo.

一面原创圆木盾背面朝向镜头，靠在工匠工作台上。弯曲木板拼缝、中央铁脐铆钉、两条磨旧皮革挽带与缝线清楚可见，旁边一只旧手套给尺寸参照。低角度侧光照出木纹和铁锤痕，不要徽章、人物、字或标志。
