Planter's must have had one heckuva advertising budget. No, there was no "Mr Peanut Pencil Company," but Planter's did insist that its advertising pencils not only be marked on the barrel (and topped with their mascot), but also with the word "Planter's" on the clip, leaving no trace of a manufacturer's mark. However, a close inspection of the clips on these two reveals who made them: the first three are Redipoint, and the next two were made by Ritepoint.
The last one, however, I'm not so sure about.
