Front living room mirror?

[Ladyfish]

Hi All,

We are still working on our new to us 1988 AS Excella 29 and want to clean the front wall. We need to remove the front mirror that is above the corner base cabinet without breaking it! Does anyone know how this is attached to the wall? There appears to be 4 clips (2 on top and 2 on the bottom); but we have not been able to move the clips.

One of the prior owner was a chain smoker and I need to get behind that mirror! Nicotine stains everywhere!

Thanks in advance for your assistance.
