A sketch on a brown paper (32.3 x 60.4 cm.) by an unknown artist but presumably French shows the reception of the ambassadors of Emperor Napoleon III led by Charles de Montigny by King Rama IV at Anantasamakom Throne Hall (now demolished .... not the same one as on page 17/406), Grand Palace on 24th July, 1856.
This sketch is a private property found at Hotel Drouot, Paris on March 11th, 1985 now shown in the gallery at Château de Fontainebleau, France.
