At the turn of the century panoramic photography was used by commercial photographers. Postcards and magazines reproduced panoramas as advertisements for real estate and the promotion of tourism. Panoramic portrait photographs were popular as souvenirs for people attending conventions, conferences, and company events. Large group portraits guaranteed many sales. After a group or event was “panographed” the photo would be displayed and orders taken for copies. I bet the guy who took the picture of the Father Hennepin Dedication below made a killing!
