Restoration Fix a photo of my grandparents

[KingOwl]

My father went to work at a hotel in the city for a month and I want to surprise him when he comes back. Could you please fix this very old photo of my grandparents? I tried to take these photos as well as possible but I can take more photos from the different side if needed. I will be looking forward to your posts.
I apologize if there are any mistakes in what I wrote, I am sharing this article with you using Google Translate.

Note: Don't worry too much about my grandfather's expression, he was sick before the photo was taken.

Hi!
You are unable to remove the rest of the glass parts that cover the right part of the frame?

Made a try in case it helps.
The original size image is too big for the forum, let me know if you want it.

Thank you for correcting. both look great. I really liked the one with the furniture on the top, it looks like a warmer environment, but I guess I'll print it because the bottom picture is exactly the same. Thanks again to both of you
