This tells me a few things:
1- His original juvenile hairline was located at the tip of the widow’s peak.
2- I can judge recession by looking at the shape, size, and location of the widow’s peak as well as when this man lifts his eyebrows high and shows the creases on the forehead.
His black hair makes everything stand out. I showed this photo because I believe that he might have had a very early recession making the widow’s peak very prominent but this is a hard call. I would look for miniaturization to make the diagnosis using a hand microscope.
