I have a collection like that one MrD ... I tossed everything newer than '75 years ago, and any I have purchased since then I toss when done, except for Rodders Journal.
Copy magazine covers on to 8.5x11. Get a gallon of Elmers. Pour some into a bowl and add some water (to taste lol) brush the back of the picture till its covered. Place on wall. Brush front of pic till its covered. Use a roller to smooth it out. It will still look like crap. Come back after it dries ... Whalaaaa, looks great and has a nice coating on it.
Course my garage doesnt look like this anymore. Lots of junk, lots of changes, and a spot for my grandson.
