Sheaffer c4 typical mining scene in Tasmania whence comes the precious iridium for Sheaffer Pens Photo © by W.D.Boyee Co. 11,000 miles away they unearth the strange metal for this pen point The South Seas yield more than romance and glamour. In Tasmania they have uncovered a strange, elusive mineral known as iridium. It is the hardest substance known to science, and next to radium the most expensive. It is out of this odd metal, iridium, that the tip of SHEAFFER'S famous"Lifetime"Pen isfashioned. It is the use of this metal,so trying and difficult to apply, that enables us to guarantee the point of "Lifetime" to last forever. It explains why a "Lifetime" point can make five carbon copies of a letter as easily as the hardest lead pencil without the slightest damage to the point, a thing hitherto unheard of in fountain pens. As a writing companion for business men,trav elers and novelists "Lifetime" is unsurpassed. Only $8.75. Other SHEAFFER Pens,$2.50 to $50. W. A.
