Investor Warren Buffett walks the convention floor ahead of the annual meeting of Berkshire Hathaway (BRK.A) as shareholders look on. Buffett visits various Berkshire Hathaway vendors on the floor, stopping by the Heinz Ketchup booth. Along the way, shareholders elbow their way toward Buffett, looking to get that one great picture. The highlight of Buffett's stroll along the floor is a newspaper toss with Bill Gates. Buffett was once a newspaper boy, so the newspaper toss is always a highlight for him. Buffett also makes sure he stops to snack on some junk food. This year marks the 50th year that Buffett has been at the helm at Berkshire.
