For sure it is not authentic Wyczolkowski. Somebody tried to follow up as oil original “view of Wawel in Krakow” which is actually watercolor and everything is different. I thought Dorotheum knows better.
I am shocked that such reputable Austrian auction house would be accused of lack of flawlessness!
