rummaging in the loft ..... I found a sediolina to decoupage made with Mickey fumentti

rummaging in the loft I found my first attempt at decoupage: a sediolina fumentti done with Mickey Mouse. I made this for my son sediolina folding. he had 5 / 6 years and then, with the passage of time I kept on the loft bathroom. I've found with my great joy, My son wants rearranges it to him in his room. Give me some advice? I did not give a fixative because I was inexperienced and did not know how. Today, after many years as I protect it? I could make it shiny? worthwhile? and how? recommend me a good product anyway?
