发明名称 Multi-directional hand-held sign
摘要 A multi-sided hand-held sign includes two substantially planar panels having a preselected shape interlocking substantially perpendicularly at a common central vertical axis and held in position partly by a handle for engaging with and holding the sign panels. Indicia typical of signs held by school crossing guards are disposed on all the planar surfaces of the planar sign panels, and a slotted top end cap is engageable with the top horizontal edges of the planar sign panels.
