Card of the month for February 2018. The Black Scribble w/ F.
Likely the most common of the scribbled out varieties. I've seen this card listed as 'scratched out' or 'blacked out' too. One of the first correction attempts for the original F-Face card. Scribbles, in general, are undervalued. Not rare, but certainly more scarce than Black Box corrections or even the F-Face cards. This scribble version clearly shows the first letter F. A correction, but not a very good cover up job.
Shown here with a double factory sawcut.
