Company officers and employees of the newly-incorporated Harley-Davidson Motor Company posed for this 1907 group photo in front of the first plant on the current site of the Harley-Davidson facility on West Juneau Avenue in Milwaukee.

Note this is the second enlargement of the original factory. Source is from the personal collection of Jean Davidson whose grandfather was Walter Davidson, first president of the company. These days a reverse image search will find many copies of the photo.
