👉 The postcard weapon, also known as a postcard grenade or a small explosive device attached to a postcard, is a rudimentary yet ingenious improvised explosive device. Typically, it consists of a small explosive charge, often a fragmented shell or a small bomb, attached to a postcard, which is then affixed to a stable object like a tree branch or a fence post. When triggered, usually by pulling or pressing the postcard, the explosive charge detonates, causing significant damage to nearby structures and people. This device was popular during times of conflict, particularly in guerrilla warfare or as a makeshift weapon by civilians, due to its ease of concealment and potential for surprise attacks.
