A Lollipop Advertising Display Board is a highly effective, space-saving type of outdoor advertising that is named for its distinctive appearance: a display panel (the "head" of the lollipop) mounted atop a single pole or flange (the "stick"). It is a popular form of retail and local area signage. The sign is almost always double-sided, ensuring the advertising message is visible to traffic and pedestrians approaching from both directions (360° visibility). Most modern lollipop boards are LED-illuminated (backlit or edge-lit), ensuring the message is bright, clear, and visible 24/7, even in low-light conditions.
