It was a real guy. There were actually a couple Valve mascots, a guy with a valve coming from his eye, and one with it coming from the back of his head (the more famous one) Apparently they just found a couple guys off the street to take photos of, but didn't keep their names or anything so nobody knows who they are. Though they did actually end up doing a 3D model recreation of the second guy for Half Life: Alyx (the VR title) https://half-life.fandom.com/wiki/Mr._Valve https://half-life.fandom.com/wiki/Mr._Valve
