Of the 3 basic black scribble variations - I'd consider this the #2 on the list. A mild correction to the first basic black scribble that included the first large letter F. It appears to be an attempt to somewhat hide the F. What is left is a partial F or a 'Loop' pattern. I've attached a combined GIF file (3.5 MB) showing the transformation of a 3 of these 'basic' black scribble versions.
