Glass Gold/Brass container with vintage picture on lid very neat artwork on the back of that picture plus the last supper statue

My grandmother used this to put Potpourri in but it also had a little basket with tiny shells in it, I am interested in who is depicted in the picture on the top of the lid I will include a close up really ANYTHING that you can tell me about this would be more than amazing as I know nothing. I don't know what I want to do with it yet I still have alot of things to go through but I really thought the artwork at the top of the container (I don't even know what you call it) THANKS. I also have a marble statue of the last supper really cool but kinda dusty and dirty let me know if that is something that might be worth money.
Sorry this is my first time ever deal with anything "antique" I found you on google and it seems like a good fit so I hope you help me with this and maybe exchange further info about antiques which just recently I have been getting into
