This is one you don't see too often. Crow imagery is, as expected, unusual. As far as I know, the Germans made only two embossed crow diecut iterations. Of the two, this is the more common, although both are hard to come by. The other is shown on page 152. The condition of this particular example is quite good. My opinion is that if a prior owner has written their name on the reverse, even in ink, it makes no difference to assessing condition if that name is otherwise invisible.
08/30 Update: I wasn't surprised that this superb diecut fetched $253. Congrats!
