1967 Topps Checklist #278
Version one is
Ole Pointy Hat as the top right part of Kaat's hat forms a squared corner. His left earlobe appears to be of the rounded, 'free' persuasion. The shadowing/hat slopes down and smoothly connects with his right ear.
Version two is
Doctor Roundness as the top right portion of his hat curves naturally. His left earlobe looks to be the 'attached' variety and the shadowing/hat is cropped differently above his right ear.
