From the surprised look on the Dad's face, I imagine that he's just told Dad what he's going to charge for this picture.
Note that Dad's coat has a smudge on it and that dirt on the negative makes the baby's arm look diseased. These negatives are old and have been stored under less-than-optimum conditions for over fifty years. Although we are trying to produce the best photographs possible, they are more valuable as historically interesting items than as frameable portraits.
If anyone knows the names of any of the people in this shot, leave us a message in the comments section.
