Jack Frost's signature

You have to look hard to see it and in truth he does not Always sign his work. But lately I have discovered the telltale marks. A dashing line at the bottom of some of his finest etchings. It is not a scribble such as doctors are said to make when they hastily scrawl their names. No! It is a DASH - a long one----- as in Dashing! I think Jack is pleased that I found it.
