1997 Sporting News Baseball Yearbook
In my opinion this is the best magazine cover to have ever showcased Big Frank.

True, it's could be interpreted as him wigging out or snapping (no pun intended), but I think the use of a portrait or on-field action shot would've been so boring. Those types of pictures have been done to death.
This image of Frank rocks.

Collector's Note: Another version of this image can be seen on the Portraits Gallery. And the one above, like all images from the Sporting News can be purchased as a large glossy print. You can order one from here.
