Actually, Pat. you picked up on something on the sketch I found and posted that made me look a lot closer at the Piser sketch posted by Josh. On zooming in, doesn't the first sketch also represent a large scar down the left cheek, rather than a 'monacle', and I wonder if perhaps the pointed bushy beard might actually be supposed to be the right shoulder area, unskillfully executed and merged with the five days growth?
That is an interesting comment, and on second glance at the sketch in your post, I agree that it could be a scar. The beard seems very pointed, but the artist isn't too talented. Maybe he wanted to convey the "foreign" aspect of the subject.
