To be the same person, certain things have to be consistent. And in these two images, one from 1972, the other from 1970, the INCONSISTENCIES are too many to not bring up question as to who this is supposed to be. Especially if he "died" in 1966.
Our source images.
The 1972 image has been converted to black & white. The 1970 image has been rotated so that his face will fall in line with where things are supposed to be on Paul McCartney. The dimensions are set by his right iris, but also can be set by the width of the eye, his nostrils, or his lips.
So what's wrong with 1972 Paul and 1970 Paul? A lot. For one, 1972's ear is massive. Their ears don't match outright. We then get to that right eyebrow. How that's achieved, without 1970 Paul appearing scrunch faced and scowling I don't know. And even if 1972 Paul is raising his eyebrow, the shape it makes is inconsistent with the eyebrow he's got back in 1970. The nostrils don't match up. They are farther apart in 1970. He could be "flaring his nostrils" but this would only widen the shape of the nostrils themselves, not the connecting cartilage between them, which as said, is wider in 1970 than 1972. 1970 also has a wider mouth, and you can tell this even with the beard.
It's the ear that should concern everyone. It's totally wrong.
