In your post, #1471 with Paul and George at the mic singing, look at the dark line that starts on Paul's right ear then drops down his neck and curves all the way around his mid neck, probably ending at his left ear.
From this pic and many others that I've seen here and elsewhere it seems clear that many of the earlier Pauls wore masks, probably some kind of liquid, brush on A.I. tech. Why ? To moreso replicate an original look of the one that the look was based off of, if there ever even was an original ? Man, this is getting intense, isn't it ?
Next, please take a look at the stopped action shot from the video of The Beatles Live In Japan 1966. It looks like the ear extension thing is shaped like a donut and it's adhered to an existing ear to make the ears stick out more than usual. Maybe this was something 'they' decided made the guys look 'cute'. In some old photos when their ears are sticking out from under their wigs it does make you notice their faces more, which surely made the young girls see them as being cute and adorable. I'm sure there is a scientific reason behind stick out ears creating attraction or they wouldn't have been using them on what seems to be all of the Team Beatles. I can't think of any older photos where you don't see those stick out ears.
It may also be possible that if what we perceive to be humans turns out to be a transhuman part organic/part machine (which I do think is very probable and very close to being absolutely true) then the stick on ear extension pieces would have been used as a complete ear apparatus instead of just an ear extension, which I see in the 1966 JPM pic in the video. There are some photos of Paul especially, where it looks like the whole ear is fake and not just a glue on rim extender.
Something else I noticed in many of the photos, there seems to be quite a lot of excess skin on their eyes between the upper eye lid and eyebrow. Underneath the eye brow hair and above the upper eye lid lashes to be exact, that's where I see it on many of them. Look at the first pic of Paul above on this page. Doesn't it look like there is way too much skin in that exact spot ? I think there is a liquid latex silicone material that comes out of the bottle in liquid form then dries to an elastic like skin. I'm certain there is a material like this but it's not available to us, that would help level the playing field and 'they' don't want that. You can really see these spots where there's too much skin in this spot when the photographer shoots them from a semi-close up side view.
The fifth pic down is a close up of a shoot that I've seen before. The other pics from that shoot show one of the weirdest Paul's I've ever seen. One of the pics I've seen before shows a waist or chest up 'Paul' with his right hand held up near his face. The hand is clearly covered with a glove. Someone on another forum swears that this is the WW2 woman spy dressed to be 'Paul'. To be honest I don't know for sure if it is her, but nonetheless it's the absolute weirdest Paul I've ever seen.
