| Comments | This is a scarce pattern. Though it's linked to Hill Publishing, because covers are known. I suspect it was actually a demonstration that Mailometer used to market their product. Hill Publishing subsequently bought a Schermack Mailing Machine with pattern 6-8-9 on or about 1/8/1910 and continued using it into 1911. |
