Happy National Pencil Day! March 30, 1858, is when Hymen Lipman received a patent for a pencil with an attached eraser. The eraser-tipped pencil is 153 years old today!
ARGH! How could I have missed the actual day?!?! Happy belated birthday to my beloved wood-encased sticks of graphite (sometimes topped with vinyl or rubber caps)!
