Years ago there was a dealer/author in NYC who offered me books inscribed by Wm. Dean Howells with a ballpoint pen. nk
Self-Correction: A couple of weeks ago I commented that a fake JFK assassination diary made anachronistic use of a ball-point pen. This was not accurate: the ball-point existed in 1963, and I meant to say the "diary" was written in anachronistic felt-tip pen. That's what I recall, anyway.
