There's a common misconception that another version of this logo which uses the city's English spelling of Munich and excludes the Olympic Rings is the official lockup of this logo. That version is so pervasive, that it was for a while used on the official Olympic website. The above shown is the actual lockup of the emblem. It's unknown where the fake lockup came from or why it's so common.
