Hi,
This is a difficult one, because so few things are possible to compare. You can't compare the damaged ear, nor the top lip because one of the men has a moustache, nor the shape of the head because of the hat. Also the tilt of the head is slightly different making it impossible to compare the shape and position of the nostrils. Despite that, I don't think that these are two pictures of the same man. The chins are quite similar, which suggests a possible family connection, however, despite the man on the left having lost at least part of one ear, it looks like the other ear is quite close to the head near the ear lobe, and further from the head at the top of the ear. The other man has ears that stick out from the head at the bottom and the top of the ear. I did consider that this might be an effect of his hat, but usually this just makes the top of the ear poke out.
The man in the bow tie has his head at a very slight angle to the photographer, which makes it impossible to see the lobe of the ear that hasn't been damaged, but I think that if the other man was turned at the same slight angle, you would still see a bit of the bottom part of the ear.
I've tried fiddling around with the pictures to overlay one with the other, and I'm sorry the software I have isn't brilliant, but here are my efforts. I do think that these men could be very closely related but the bit to look out for is the difference in the shape and position of the ears in the red/green transparency. My personal feeling is that the difference is too much to be explained by the slight forward tilt of the 'ear' mans head. The lines on the first photo are part of my checking that they are lined up as closely as possible.
Any comments?
Regards
KJ
