Crew members work on the L’Hermione as a giant rubber duck sails up the Delaware River between Camden, N.J. and Philadelphia during a tall ships parade, Thursday, June 25, 2015.
The Dutch artist Florentijn Hofman created his first giant inflatable duck and displayed it in Amsterdam in 2007.
Since then, versions of his creation have been shown in far-flung ports of call, from Sao Paulo to Sydney. According to published reports, it prompted a rubber ducky craze in Hong Kong, where it drew throngs for over a month. When it deflated in Taiwan in harsh weather, media accounts say, there were calls for 10 seconds of silence.
