Davey was a comic strip that ran in the Catholic Saturday Evening Post back in the late 40s/early 50s. A few sample strips have been posted at
I'm Learning to Share blog. Judging by the samples presented, it started out as a fairly lighthearted strip, but as the years went by, it became decisively more serious, with the strip's protagonists' facing off against nefarious Communist spies who wanted to bring down America... for some reason or another.
This strip in particular caught my attention for several reasons. First, I just love how the unnamed Russian intelligence agency was presented as way more competent and resourceful than KGB or GRU ever were. Second, I got a chuckle out of the the photo-manipulation mentioned in the strip because this was something the Soviet government accused Americans of doing to make USSR look bad. And finally, look at the second panel in the third row. I mean, I understand that this is a Catholic comic strip, so of course it's going to biased in favor of the church, but come on now.
