John Jewell Penstone (1817–1902) was a portrait and genre artist who worked with paint, but is known mainly for his engravings, and has been associated with the Pre-Raphaelite movement. The National Portrait Gallery has two of his stipple engraving, and a lithograph (printed by Nosworthy & Wells). Using only the above description and what you know about the world, "John Penstone preferred engravings to paintings." is definitely correct, incorrect, or inconclusive?
