very new to this . i have come acrooss a very old deteriorated glass top wood case . In this case is a neatlly put mint conditioned u.s flag . on this flag is a pic of an eagle with a flag in his talons . pinching the flag in the middle it has thriteen stars on it . with the eagle facing to the left . below the pic is a banner with some latin words on it . does anyone know what the heck kind of flag this is or what it represents ?.......... trash or treasure ?
