Having seen a comprehensive exhibition of his prints not so long ago, I can say to see the real thing is truly inspiring stuff. Of course some people think he couldn't print, and advocates of the zone system may be disappointed, but if passion, commitment and poetry is what appeals to you, it's there in abundance.
And I am very disappointed I will not be able to make it, not being very close to NM. Saw the centenary show in London a few years back and this looks to be a very well organised and supported exhibition.
