Photograph of Mailsters on parade
To promote their newest mail carrier vehicles, postal officials organized a group of mailsters for an appearance in a holiday parade. The mailsters bore banners of Santa's reindeer, with the "Rudolph" vehicle in the lead. That mailster has been fitted with a red cover over its top front headline to mimic the fabled reindeer's red nose. Washington, DC postal officials took advantage of a Christmas parade in suburban Maryland to show off their new three-wheeled vehicles.
