This version has the ‘Beware!’ caption added.

Here’s another advertisement from World Countdown, July 1967:
From World Countdown, August 1967:
Note the presence of Ry Cooder’s replacement, Gerry McGee (second from the left), who played with the Magic Band for only two live shows and did not appear on the record.
At the bottom of this ad have been added the words “20,000 HEADS VOTE HEAVY IN 10 DAYS” which gives the impression that the album had already been released at this point and is selling well.
From Billboard, August 1967:
This weekly feature in the music business paper, Billboard, lists Safe As Milk as one of the recent albums “… not yet on Billboard’s Top LP’s Chart, have been getting strong sales action by dealers in major markets.”
From World Countdown, September 1967:
Thanks go to Richard Morton Jack for sending some of these adverts along.
