Thrilling Murder Comics

[mrbillscomix]

Here's another issue like the Legion of Charlies I posted awhile ago.  I'm assuming that the copy on the left is the common one since I have more of it than the other. Is this another variant issue?
I haven't noticed anything else different between the two issues.

[50Cent #II (1st print)]

Looks like the right one simply doesn't have the red on it.
Interesting...
