Interesting shape of bread

When I was looking at an old folder in my computer, I found an interesting photo of bread. It was more than 10 years ago when I took this photo. I bought this bread at the local supermarket in Japan. This is a bread which at first glance appears to be ordinary bread, but it caught my puzzle sense and that's why I bought it.

 

This bread looks a bit difficult to make its shape. It seems possible if there is a long piece of bread dough, I can make this shape by the same method of one-stroke sketch. What I mean is three-dimensional-one-stroke sketch. I don't know if there is a word "three-dimensional-one-stroke sketch", I just made it up now, you know what I mean?
I'm not a hundred percent sure now, but I think I looked at the bottom of this bread and saw there are three types of bread dough combined together. So, in fact, it might have been not so difficult making this shape, I guess.
As you noticed, people like me who are interested in puzzles pay attention to something that other people don't care about. I was excited when I ssw this bread at the supermarket. If someone who was there and saw me excited looking at the bread, what did she or he think? I hope she or he didn't misunderstand I was a strange person or maybe I was.
The world is full of interesting things through a puzzle sense of eyes.
