Communication of the departmental governor Sir Jorge Mendez Castaneda on 21 April 1997: "Based on the mythical coat of arms of the city of Coban supposedly granted by Charles I of Spain. Until 1936 the world image showing the American continent carried the emblem of the Dominican order that had christianized the region called then Texulutlán. The arms were recently revised by the lawyer Agustín Estrada Monroy, who included some quetzal bird feathers, a royal crown and a rope with knots on its ends, but his proposal was found too different from the original design from Charles I and rejected."
