I recently got this large Socony wall map. Measures aprox 34" x 41". Was wondering how to protect it so I can display it without it getting damaged?

I purchased it off ebay and thought it was going to be canvas type material like the old school maps were or something stronger than it is. It is a very thin coated paper. It is a little brittle as well now that it is 86 years old. I'm scared if I just hang it on the wall as is I'll damage it someday just working in my garage.

Does anyone have and display maps like this in there collection. I could get it framed but I think that would be very expensive based on the size it is.

Thanks...
