发明名称 Novelty writing instrument having an appearing and disappearing personal name
摘要 The body of a writing instrument is provided with the novel feature of having a person's name appear thereon and disappear therefrom in an apparently magical manner. The instrument may be a pen, pencil, felt tip, ball point, or the like and includes means for causing a person's name to appear as though it is being written on or erased off the body of the writing instrument as the orientation of the instrument is changed.
