Yes, I have this story at home in my collection, I’ll check, but it seems they hadn’t the feature they had in Superboy # 161 (see above), their hair was blacker, their face less wrinkled, but we still recognized them. So in certain stories (like Superboy # 161 for instance), Pa Kent looks like a Hollywood seducer and Ma Kent as sexy as Katherin Hepburn. Besides, it is in this kind of story that Krypto has pointed ears, and I noticed it is often when Wally Wood was the drawer.
To clear the point, we’re used to see Krypto As a kind of Labrador or epagneul with this feature:
But in the other stories, essentially those drawn by Wood, Krypto looks like a kind of Dogue like this:
By the way, what is Krypto’s exact breed? Interesting question…
