Montana still reqires the pair of plates to register YOM. You just have to affix the rear, but they still need both to register. They only made singles with the Korean War metal shortage during 48-50. Some years a windshield sticker was affixed for current registration. And I found a nice single plate for future registration, but in a small ranching county, it's impossible to find a pair. They were unique every year until the late 50's, with the unique "Prison Made' stamped on the bottom. Washington only reqires a single for YOM, and varied with different plates with metal tabs until 58 with stickers.
