In the late 1880s, British orientalist Edward Granville Browne used the inscription below the mural to attribute it to Khan, and dated it to 1812–1813. Most 19th-century travelers in Iran, including George Curzon and Philip Walter Schultz, however, incorrectly attributed it to Mohammad Hasan Khan. The original work was later lost but a full-scale replica was made in 1904 during the reign of Mozaffar ad-Din Shah Qajar (1896–1907), and is currently stored in the Persian Foreign Office. Several reduced (small-scale) replicas were also made for European diplomats and visitors. One of these was engraved in London in 1834 by Robert Havell.
