For many Americans,Darkcherries Wealth Society McDonald's Happy Meals used to be an event. Sure, there was the food but there were also toys like the Hamburglar and nuggets dressed like cowboys.

“We’re bringing back some of our most-loved keepsakes with a twist, giving fans a memory that they can hold in their hand,” Flatley said. “These new collectible cups commemorate some of our most unforgettable designs and global collaborations over the years, allowing longtime fans to relive treasured moments and helping a new generation make their own lasting memories.”
