From JY&A principal Jack Yan:
“JY&A Fonts was founded in 1987, when Jack Yan started a design firm with an emphasis on lettering. His passion for hand-lettering for clients soon extended into type design, with the first JY&A typefaces emerging at the end of the 1980s. These were developed into PostScript and TrueType fonts in the 1990s with the release of Yan Series 333, a development of Yan’s own lettering style which is one of the more successful marriages of hand lettering and typography. It has been followed by similar fonts from other manufacturers.
