The most recent addition to the growing collection of tributes appeared Wednesday in Serbia. Unidentified street artists painted a graffiti mural of William's face on a wall under the Brankov Bridge in Belgrade overnight.
Fans of the late actor quickly shared the touching tribute on Reddit and social media.
Small memorials to the Academy Award-winning actor, who was found dead in his California home Monday, have appeared on the Hollywood Walk of Fame, outside his home and at real-life locations of some of his famous movie scenes. In Massachusetts, Bostonians penned chalk messages near the iconic bench featured in "Good Will Hunting" to memorialize the funnyman.
UPDATE: An RT video showing footage of the artwork previously included in this post has since been removed from YouTube.
