Led Zeppelin III #1 Immigrant Song (backward lyrics in red)

YouTube comment ... The " Hallmark " of the album, as mentioned in one line backwards in this song is this ---- when you look at the album cover ( when there's no words over it ) and you pause it, without any words over it, you'll notice where the three " e ' s " are in the name Led Zeppelin, as the album is turned backwards, they are, without doubt --- 3 " 6's " turned backwards as well as upside down. With the Roman numeral III beneath them . There are also a couple of 5 pointed stars with a circle around them.
