I don’t like either of them. The Lucas is close but the top of the G is off, IMO. The group shot is so dark I can’t really see the Ford or Herring well enough to be certain, but from what I CAN see, I don’t like them. Herring is not uncommon, so why he would choose to sign in a dark spot is a red flag to me. Wait for others to chime in, but I would not want either in my collection. Even if authentic, there are much better examples of all to be found at reasonable prices.
