Advertising novelty
摘要:
Strips of burstable, gas-filled bubbles are adhesively secured to the margins of a substrate (e.g., a paper cocktail napkin) having a printed advertising message and are adapted to be popped by the user to focus the user's attention on the napkin and the message printed thereon.
