Without being bias of my PC. These two are absolutely my favorites. The '58 batting foes to me is just an absolutely stunning card in every aspect.
And Hanks '61 just has something about it that is addicting to the eye to stare at. Something about the background and colors they chose just make it pop so much.
Aside from these I would definitely give honorable mentions to Willies '58, Clemente's '57 and Ernies '67
