If it's an antique and means that much to you, then go have it professionally framed. They will put it in a shadow box, use acid-free materials and conservation glass that will protect from damaging UV rays. My MIL did this for my husband and I with all our childhood mementos. They're really cool and get lots of ooohs and ahhs from visitors to our home. My husband's has his cub scout uniform, soccer jerseys, pictures, and a tiny cast from a broken wrist at age 4. Mine has my girl scout patches, high school letters and awards, and patches from all the places I traveled as a child.
Wow, I went off-topic and that was probably TMI, but oh well.
