How to protect the face of a bat

I recently got this signed bat, and I'm really happy with it. I live in a non-cricketing country, and equipment is simply non-existent here, so I can't buy another bat so simply, but I still wanna practice on my own with the one I have. What is a good way to best protect the signatures from wear and tear, and at least slow down their fading? Other stickers? Plastic? Lmk.
