Yes, I think so. This is a case where "the ears have it." Ear shape and also hairline shapes tend to be pretty individual and distinctive. I worked as a photo archivist for more than 25 years and this is a technique I often used for identifying persons in photographs and I continue to use it working on family history.
My husband's uncle by marriage had such a distinctive hairline that I was able to spot it, even in negatives, with no trouble.
