Further provenance: sold by a Paris antiquities dealer to the current owner.The name Iahirdis means "der Mond ist es, der sie gegeben hat". His mother name is "Shesemtet" (dangerous lion goddess).
This shabti dates to the 30th dynasty and shows that the quality of shabti making could still be very high.
No published parallels are known to me. I know of two other unpublished parallels. One was sold by a US antiquities dealer from a former Belgium collection (smaller in seize and less in quality) and another nice example by a different Paris antiquities dealer.
