It being Mother's Day weekend and all, I have a feeling the above photo of Charlie and his mum will be making the rounds on Chaplin social media sites. Unfortunately, this isn't a real photo of mother and son but a composite, meaning it's two separate images that have been spliced together into one. Thanks to fellow photo sleuth, Dominique Dugros, who made this discovery and even found the original photo of Hannah (below, it was flipped for the composite).
The original version of the Charlie side of the photo is still a mystery. Although it appears to have been taken at the same time as this photo:
Sadly, what all of this means is that there are no real photos, at least that we know of, of Charlie and his mother together. All of the existing ones are composites, including this one.
