Self portrait 1924

I have no idea what to think of this print. I suppose it is a lithographic copy. There are  obviously 2 versions of Kollwitz’ 1924 self portrait. 

I found a similar (or what seems to be the) original in the Chicago Art Institute. This is a (without signature) copy of the more “sophisticated”, more detailed (so later ?) version. Perhaps one day the origin of this copy will be explained.  

It is nice to be able to represent something original (as near as can be) by this most famous and celebrated German women graphic artist.
