A tall opening with an upper sweep
The enlarged opening loop reaches well above the low cursive forms that follow. An upper sweep runs across much of the image, while the end of the name returns near the lower writing line. Compare that upper framing movement with signatures framed by a lower underline.

Opening, letter body and finish
The opening is lower than the typical letter body. The opening-to-body ratio is 0.52×, while the whole image is 3.96 times as wide as it is tall. The rightmost ink finishes above the writing line; look at this ending separately from the slant of the letters themselves.
Loops and the lower flourish
The sample contains 8 enclosed loops and 8 main ink groups. The letterforms carry the main horizontal movement; there is no long lower underline detected beneath their band.
