I am searching for some information regarding a framed mirror about size 10X11 with a top emblem and a bottom emblem.

We did a little searching and found out that if George VI is the latest monarch mentioned on your mirror, then it will date from sometime during his reign, however if the warrant from the current Queen is mentioned, then this means it could date from any time between the 50s and the present. To narrow down a more specific date, we would need to see a picture. It sounds like you have a branded bar or pub mirror, which were (and still are) often used as an advertisement.
