Prov.: US collection
No parallels are published for this shabti. However, i know of 4 others each with different facial characteristics. The clearer glyphs on especially one of the others makes the owners name and titles clear (with the help of Dr. M. Raven): Yay, high Priest of Letopolis with the rare title of "Mouth Opener of Horus, lord of Chem".
A parallel page with an overview of the other shabtis is added HERE.
The voluptous body tend to date the shabti to the 18th Dynasty but without further provenance information this cannot be confirmed.
