What differs or remains uncertain
Both are now shown in photographs; the modern illustration of the tablet is kept as a second view, and the boulder's only image remains a 1919 photograph.
A small tablet and a relief boulder have different compositional constraints.
Transmission check
Transmission not yet assessed
The comparison is not yet identified or dated well enough to exclude ordinary transmission, later borrowing or an image-selection effect.
What would move this forward
Acquire a museum accession record and dated context for the tablet.
Compare the photograph with the illustration to see what the drawing restores or emphasises.
