The original Penobscot Building in Detroit, Michigan, completed about 1906, "was named after the Penobscot Indian tribe and region of Maine, the boyhood home of one of the investors. An interesting feature in the Indian-themed detail of the building is the occasional appearance of a swastika, a symbol important to the Penobscots long before it was adopted by the Nazi party." The decorative symbols feature right-facing arms and are tilted in the same manner as the Nazi flag, leading to confusion over their origin.
