Finao sells one, though it's termed "mystery glass" because it has a foggy texture on one side so you can't see through it. I'm not sure about a clear glass cover if that's what you want.
There are many acrylic options with the photo behind it. Are you sure they specifically want real glass? Because I've heard many clients refer to the acrylic as "glass".

I think that's what they are looking for.
Finao, Graphi (Yeah I know) offer this acrylic cover album.
