Black and white cookies/cinnamon pretzel cookies

I passed Zaro's in Grand Central Station and saw two quintessential NYC pastries. Being NYC-centric, I wondered if black-and-whites are available in other pasrts of USA. I was in Germany last tear and was suprised to see them for sale in local bakeries. The twist was, they were called: "American Cookies"!

As for pretzel cookies/pasteries, I'm talking about a sort of large twisted flaky pie crust (sometimes with bits or streaks of chocolate) also crystal sugar and cinnamon that is shaped like a large pretzel. They are delicious and I find much harder ro find than black-and-white. Has anyone seen these elsewhere?
