Peter's had an odd geometry because the store was located on one of NYC's sharpest triangles. NYC's downtown area doesn't have the strict grid arrangement found uptown; St. James Place was once part of the colonial-era Post Road to Boston, which meandered thither and yon all over the east side of Manhattan Island. When other streets were laid out the Post Road met them at sharp edges.
A Forgotten NY reader said that Peter retired and sold the building.
