These pictures are all from "The Office" and seem to indicate that the family was in the business of selling or distributing water heaters. Most of these pictures are too dark to make everything visible so I enhanced them a bit to illuminate the details. "Enhanced" might be too generous a term when all I did was use built-in functions of the GIMP software. The last slide in this series was annotated with the names of the people pictured. Another slide contains images of what looks like a poster-size advertisement for gas-powered water heaters.
