What do you make of the “Dunham” signature?
The “D” in Dunham looks like an image right on the paper itself, while the “unham” looks as though someone went into to photoshop and darkened each letter on a pixel basis. I mean you get the real crisp edges in the “unham”, but the “D” has the grayish squares that you normally see in a pixellated image.
Without seeing the original document, it just looks like a weak start signing the name to me similar to the A in Ann. The line is narrower than a single pixel width, therefore it shows up as gray.
