PostIt™ Informal Regular and Bold
These two fonts were commissioned for 3M Company's exclusive use in PostIt™ Notes advertising. The design studio, Little & Co. of Minneapolis, provided hand lettering samples from the guy who had previously created lettering for the ads on an as-needed basis. It's still in use, as far as I know. (I once spotted this font used on a book jacket. I wonder how that happened?)
Created in 1996.
