Antique Persian Brass Tray

This stunning example of hand-embossed art is made of brass with rolled edges. Unfortunately, I am not familiar with the significance of the people in the images, if there is any beyond purely decorative. It measures 20 1/8" (51cm) by 15 1/4" (38.7cm) by 1 1/4" (3.2cm) with an internal depth of about 1/2" (1.2cm). While in overall great condition, there is some corrosion needing removal and a small "crack" on the top left edge (pictured).
