This panorama of New Orleans, Louisiana was captured by Detroit Publishing Co. between 1900 and 1915. Scans of the 5 negatives were downloaded from the Library of Congress and stitched together into one panorama using the open-source Hugin software. 
One noticeable artifact of the stitching is an incomplete trolley in the far bottom on the left side of the image. Other artifacts may also be present.
