An unidentified actor in costume for what appears to be the part of Macbeth. While not positive I base this as yet
unidentified actor's role in Macbeth based upon his use of a Scottish dirk - the hilt of which is just visible - as part of
his costume.

An interesting detail in the image is his use of a modern safety pin to hold the upper part of his tunic closed.
