 Each coach would travel through its assigned neighborhoods, with the driver periodically pulling (twice) on a large handle which sounded a distinctive whistle or stop at a house where a Helms sign, a blue placard with an "H" on it, was displayed in their windows.Customers would come out and wave the coach down, or sometimes chase the coaches to adjacent streets.Wooden drawers in the back of the coach were stocked with fresh donuts, cookies, pastries and candies, while the center section carried dozens of loaves of freshly baked bread.
