You're totally correct, below is a pic of her from circa 2010s where she poses with one. On the older other one you can spot a pack of Marls behind the tea cup on the table.
Great pictures, Manny! I wonder if anybody knows of any interviews, articles or videos in which she talks about her smoking? I know a couple of commenters on her pictures here have mentioned it, and I'd love to hear more about it.
I don't think Hannie ever talked about it in interviews. The only thing I can conclude is that smoking certainly is (Was?) not uncommon among Dutch FBBs - reflecting a trend in the Dutch general pop at the time possibly - I had a picture of Juliette Bergmann indulging in smoking one from a old BB magazine. In the pic she is casually dressed and seems to be attending some kind of party. The photo looked quite old as it reflected a time when indoor smoking was still common. I'll try to find this one again.
