miracle of sorts

Twin brothers Phil and Mick Cahalane found this family photo of their grandfather that they say is over 100 years old. The picture shows grandpa holding an amazing string of fish he had caught somewhere in Scotland. As the close-up in the above photo shows, however, there seems to be a figure on the man's left shoulder that some say resembles a saint. Some have even gone so far as to say it is St. Teresa of Avila.

There are many faithful who will, no doubt, say that this is a miracle of sorts. I think it's an amazing illusion.
