Social Security Administration Guide: Alternate Text for Images

Signatures

For signatures that are rendered as images, add the word ‘signature’ to the image, followed by the name.

“Signature: Pastel Bosken.”

“Pastel Bosken”
It doesn’t include an identifier that it is a signature.

“Scruffy, poorly written signature of Pastel Bosken”
The extra information is not needed—and this is not the place for a handwriting critique.
