You don't see too many photos of Steve Jobs and Bill Gates together, and you definitely won't see many more like this. This photo was posted a few years ago by Minimal Mac and is a classic that I've never noticed before. I absolutely love that '80s Breakfast Club-inspired cut on Jobs and the always-present nerdiness of Gates.
Other than a credit to Croatian designer Alexander Pieri, background details surrounding the photo are not known.
Update: Thanks to All About Steve Jobs which pointed out that the photo is from the August 1991 edition of Fortune that celebrates 10 years of the PC. The article has a great conversation with the two personal computing giants.
