Provenance: ex Dutch collection HK, acquired by HK from a Dutch dealer in antiquities in Utrecht in 1968 together with a similar smaller shabti (unpublished) apperently for the same owner.
This shabti is for the same owner as the Bak-Wer published in Schneider (18.104.22.168). This is line with the period that the Leiden museum acquired its pieces and the ones offered by the Dutch another dealer Moger at the end of the 1960's/ early 1970's unpublished so far, see also SC/120 and SC/122.
The reason to publish another of this series is that for the first time a blue faience figure appears for this owner, all others known are from white faience. For the 19/20th dynasty it is not uncommon to have white and blue faience shabtis for the same owner, for example the Khaewaset and Hori shabtis.
As a final note, please note the black paint at the back below the seed back. I have seen other NK shabtis with similar markings. In fact all shabtis for this owner, see also SC/120 and SC/122 and the unpublished ones have a similar marking. As they do not appear to be a hieroglyph they could be the signature of the ancient painter of the glyphs.
