As far as I know, this mural by Sam3 is the tallest in America, if not the world. It was painted this month in Atlanta for the Living Walls Conference. Yes, there are murals and even illegal graffiti that cover more square-footage, but in terms of height, this 15-story-tall mural has everything I can think of beat. So is this really the tallest mural in America or possibly the world? Let me know in the comments if you know of a taller one.
Update: Thanks to a anonymous commenter, we’ve found out about this mural in Chicago, which is 200 feet tall, and the mural on the David Broderick Tower in Detroit. Looks like one of those murals holds the record of largest painted mural, for now.
