Thanks to brett 75, I decided to look into the 1960 Topps Al Kaline card and he was right on the money. It has quite a few variations. They are all concentrated in the upper left red corner, so focus on that area. Here is what I found so far:
1. Normal version with a relatively sharp corner. Just a nub of red extends into the white.

2. Normal version with a rounded corner.

3. Really tough one to find. The corner is sharp and it's dark, not solely red.

4. A little red nub on the corner and a small and faint red cross appears.

5. Blatant and large red cross appears.

6. Dark horizontal line extends slightly outward and a faint yellowish/blue (not sure truly what color it is) line goes vertically upward.
