Mickey Mantle Memorabilia question on items
 

There’s a local auction coming up in a week that has two Mickey Mantle items that I’m not sure the value on if really any and was looking for some input. Both items are from Pre Majors. Any help on what kind of value would be much appreciated. One is a Independence 1949 game brochure and the other a 1950 Joplin Miners game brochure.
