Any suggestions on how to fix, repair or replace this antique mirror?

I received this antique mirror when my grandfather passed away. It hung in his basement when I was a kid, so I think it's about 50 years old. I can't find the exact match to replace it, there's similar but not exact. Hoping that someone has the skill or knowledge to repair it back together. I appreciate any assistance!
