The Chicago exhibition was sufficiently successful to prompt businessman Charles L. Willoughby to commission a second version, which opened in Boston, Massachusetts, on December 22, 1884. From its opening until 1892, approximately 200,000 people viewed the painting. The Boston version was housed in a specially designed building, the Cyclorama Building, on Tremont Street, and was the site of popular public lectures on the battle. Two additional copies of the cyclorama were made: the third was first exhibited in Philadelphia, Pennsylvania, beginning in February 1886 and a fourth debuted in Brooklyn, New York, in October 1886.
