Fake or real?

[ASF123]

Hi all - today I received these 3 cards from an eBay seller.

I'm 99% sure the '68 is a fake - the focus isn't sharp, and under magnification the print pattern is blurred and barely visible rather than sharp. Red flag #2 is the back, which has faint print dots where a blank cardboard background should be, behind the name/info at the top and the cartoon at the bottom. And then when I went to take a photo with my iPad for this post, the telltale cracking effect became visible. It doesn't really show up in the version below because of file size limits, but it's definitely there.

I'm therefore suspicious of the '64 and the '65, of course, but I can't seem to find any obvious signs, even under magnification. The print patterns look like others in my collection, and the backs are blank where they should be. No cracking effect in the iPad photos, and the dot pattern on the surface looks similar to others. Are there other signs I'm missing, or maybe there are fakes that are better done than the '68?

The Mays does have some offset in the printing that is visible in the white outside the lines of the W and M in his name on the back, and under magnification, each letter in his name/position has a pink outline under it and a blue one above it.

Any input is appreciated, as always.
