Saw the exhibit Impressionist painting in the Industrial age. Well displayed and informative.
Favorite artists are Monet and Pissarro.
I used the Mobil digital app instead of a paper ticket. Then I had to produce my Membership card to identify myself.
I was not happy. In future I will print ticket since the mobile ticket is not sufficient.
Was embarrassed being on the spot at the front of the line.
I think the gallery should correct this habit.
This is the reason I rate 4 stars and not 5.
