Record companies, particularly in the 1960s, would release records under a variety of labels. (Example - An Elvis Presley album might first be released on RCA and later re-released on Camden records) Usually the cover would change.
This happened for re-releases and distribution in foriegn markets, as well as when smaller labels would be bought up by competitors.
Since Ike & Tina were distributed on 11 different labels over the years, it's reasonable to assume that the album you speak of was released more than once.
