Regarding ".... Smith," whoever signed it was having trouble with the ink on the "S," first hump of the "m," and the "h."
What keeps catching my eye in "...Smith" on the card and the found example is:
- The stop/go where the "m" ends and the "i" begins.
- The second hump of the "m."
- The "S," including the height of it.
The book and the found example:
- The h in Smith travels above the line consistently
- The crossed t has a similar angle, above the t and through the h.
- The entire name travels on the line consistently
- The F in Frank were partially done, lacking pressure in the loop, fading off.
............
- The S in the book example is different from the others, but the S on the card and found ex. are similar.
- The F in the found ex. is different, but the F on the card and book are similar
- The end of the h on the card is different, but he didn't have a line to write on.
In the few instances where one seems different, the other two are similar.
