Two Tales of Capture
There's a similarity between the two stories in this issue. In the Jonah Hex story, there are two groups who want Hex dead, and one of them has captured him when they encounter the other. In the Tejano story there are also two groups who want Tejano dead, and one has captured him when they encounter the other. Both stories also take place near the Texas/Mexican border. There are quite a few other similarities between the two stories, but you get the idea. While both stories are fairly average westerns, in terms of writing and art an average issue of Jonah Hex is still a bit better than the average western comic, which probably accounts for the title's longevity. Practically speaking it's the only Silver Age western to survive uninterrupted into the modern era.
