Check out the below forged Mickey Mantle and Roger Maris baseballs listed by Ebay seller K2gnh_22.

As you can observe, the forged also inscribed "Best Wishes."  This is laughable at best.

One of the most laughable Mantle forgeries you will ever observe.

Here is that forged Roger Maris baseball listed by Ebay seller K2gnh_22.
