“The memorabilia displayed at each Hard Rock International property holds a special connection to its specific destination and allows visitors a glimpse into the music and the pop culture surrounding it,” said Matt Harkness, president of the Atlantic City casino. When the Hard Rock opened June 28 in what used to be the Trump Taj Mahal, the casino opened in 1990 by Donald Trump, it brought with it a large display of items from what it calls the world’s largest collection of music memorabilia.
