While the vast majority of work Ditko did for Charlton in the 1970s was in the fantasy/horror titles, he did dip his toe in a lot of the other genres that Charlton continued to produce.
TEXAS RANGERS IN ACTION #77 [1970] has an 8-page Ditko story called "Enemy Ground", which opens up with the outlaw Lopez and his men gunning down ranger Hyte Tolliver in the streets of a small Texas town. After the ranger's body is carried away, Lopez and his men continue to run roughshod over the town. After they threaten the local barkeep, his daughter asks Tolliver (still recuperating in secret in a local widow's basement) for help, and being a gallant ranger he goes to confront the bad men, prevailing with some help from the barkeep.
Pretty standard story, but it's always good to see a Ditko western, the action and characters fit nicely with his style.
The cover of this issue is also partly Ditko artwork and part Pat Morisi, although just taken from the splash pages of their interior stories, as was often the style at the time.
