Need to scribble some things with a Sharpie...on a billboard? 40 feet high? YWFT Signature has you covered. YWFT Signature was meticulously crafted as a custom handwriting typeface for use at both small and very large point sizes. Originally created in 1998 for the advertising agency Fallon, YWFT Signature was later augmented with the addition of an alternate family, allowing for the substitution of repeating letters for a more natural writing feel.
