    Abstract: A hanger device is provided for harmless removable attachment to sheet material. It includes a hook member for releasably suspending an article, a magnetic base member integral with the hook member and engageable with one surface of the sheet material, and a ferrous backing member engageable with an opposite surface of the sheet material and generally coextensive with the base member. In this manner, the base member and the backing member are drawn together by the magnetic flux and held firmly but removably in engagement with the sheet material. In one embodiment, the base member remains substantially fixed relative to the backing member. In another embodiment, the base member is easily rotatable relative to the backing member. In still another embodiment, the base member includes a sheet of flexible magnetized plastic material having a mounting surface engageable with the sheet material and an opposite passive surface to which a boss element integral with the hook member is bonded.
