The Exhibit Supply Company put out at least three different poses of Mickey Mantle within their loosely defined 1947-66 issues, this being the earliest of them.  Featuring a classic image of the young Commerce Comet, this PSA 4.5 can be found with two signature variants, with the "c" and "k" of his first name connected or not.  That pair is connected here and is set atop fabulously composed image.  There are some light creases and a small area of staining on the reverse but this is a sweet looking Mick.
