Identifying Autopens
Current in mid 1965 (seen used on a NASA letter at this time).
The first example shown of this autopen is an unusual one as it combines a hand written inscription "In appreciation" with an autopenned signature.
This Gemini 4 EVA photo includes a pre-printed Ed White inscription and signature - "With appreciation for your efforts towards zero defects". Examples were given to many of those who worked on the Gemini project at the time.
