When is the last time you heard of IBM? They were once the biggest computer company, and now, they're a bunch of posters. Do they still make computers? Either way, at Reagan airport, the gate area from where I was leaving had this display of posters that went around in a circle. Of course they repeated, but I think I photographed them all. IBM might be hard to find these days, but these posters are done right. Great graphics that make a fine study of how colors react to and with each other.
