Be warned, this harkens back to a time when computer monitors were cathode-ray beasts, floppy drives proudly stored your data, 1.44 MB at a time. I suppose you could call this my wayback machine.
Unfortunately, many of my projects for IBM were for RFPs and executive presentations under NDAs, so are not included here.
The company had a very strict set of brand standards, even for internal and private communications and part of my role was to act as one of the gatekeepers of those standards, for myself and others in the department. At the time, fonts were limited to Bodoni and Helvetica. IBM has since also adopted Lubalin Graph and Janson, to update and temper their corporate image while maintaining a professional appearance.
These designs are of course dated and very corporate, but in keeping with the trends (and my experience) at the time.
