A self promoting omnibus manufacturer in New York used this as self advertising while moving 120 people at a time. I count 31 on the roof alone.
the banner on the bottom says Pride of the Nation, and that reminded me of where I'd seen this omnibus before, the Stephenson omnibus that got the company started on making trains and rail cars
the above was modified so it could be pulled by the Knox tractor instead of a team of horses. How did I come across that? I remembered that I posted about Stephenson in 2015 http://justacarguy.blogspot.com/2015/05/the-development-of-john-stephenson.html
and this impressive horse drawn bus in 1850.
