One of the most prolific hit-makers of the late 60’s and early 70’s was Three Dog Night. They had 18 consecutive top-20 hits with several number ones including “Mama Told Me Not to Come” and “Joy to the World.” In 1970, ABC/Dunhill released the Three Dog Night album, “It Ain’t Easy.” There were two different album covers. One shows the group fully clothed and worth no more than $15.00. Another version pictures three vocalists, four musicians and one unidentified girl—all nude. The cover can sell for $200.00 today. Both are shown here.
