Parker Advertisement, July 17, 1920, Parker Lucky Curve, Literary Digest magazine. vert measures 3 x 11 inches, the full page measures 8 x 11.5 inches. Bold illustration of a Parker nib and pen. "Science me the Parker Always Clean, Always ready, Quick to Fill, Safe to Carry". Love the note about how 900 of their 20,000 dealers render local service. Excellent condition for an of this age.
