You need to consider the fact of change in marks from picture 1 that the news sign is a "and" sign; whereas the sign on the anon pic is a "plus +" sign … you will have a extra stroke in the sign for 'and' with that said if you can image to remove that stroke they do look the same.
also consider did Trump sign the back of picture at the rally and so then it signed while holding the picture so may have slurs. If however done afterwards signed they still look to familiar.
