The only illustration in existence was scanned from Juan Manuel Zapatero's 1964 book "The Caribbean War in the 18th Century." The illustration only existed in black and white: the color version had been lost.
The original coat of arms of San Juan was granted by Spain in 1511: making it the oldest heraldic achievement still currently in use in the Americas. My illustration is similar to the official arms of Puerto Rico and the arms of the City of San Juan, but we intended this art to be a celebration of the history of San Juan, and as faithful as possible to the image of the garrison regiment arms painted sometime between 1798 and 1804. We researched and re-constructed a color version of the arms which I painted and shipped to him in 2018.
