ServiceMaster Clean, a janitorial services provider, will release more than 150,000 comic-book style posters to facility and office managers throughout 2002.

The posters feature these managers as superheroes, including scenarios such as "The Cloning Machine," illustrating the ability of managers to be everywhere at once, and "The Time Traveler."

The posters are part of a campaign to market ServiceMaster Clean service centers, according to the company.
