From Life, May 28, 1956, a full-page ad marking 100 years of the Eagle Pencil Company:
If you’re wondering . . . those cedar slabs are called pencil slats.

From the four corners of the earth we gather these rare ingredients for Eagle pencils!
Smooth, silvery graphite from Ceylon and Madagascar . . . jet black graphite from Mexico . . . slick, oily clay from Bavaria. Malayan rubber . . . straight-grained American cedar . . . pigments from nature’s secret storerooms everywhere.
Even the arctic seas yield spermaceti, the whale oil wax that helps make Eagle Mirado the smoothest-writing pencil you’ve ever used. And from the foundry’s inferno comes brass to make the gleaming tips with Eagle’s familiar Red Band trademark.
But the rarest ingredient of all is not shown in the picture. It is Eagle’s 100 years of experience . . . experience in refining, blending, assembling . . . in research, testing and quality control. That experience is the ingredient most important to you.
There is a specialized Eagle pencil for every purpose: Mirado, the world’s largest-selling writing pencil . . . Verithin, the strong-pointed colored pencil . . . Turquoise, the finest of drawing pencils . . . and hundreds of others. To find the most efficient of these for your kind of work, write for your copy of our full-color booklet, “The Pencil Selector.” It’s interesting, helpful, and free.
