Whenever I see this, The guy holding up the painting looks like he's thinking: Aw crap! I have to stand next to this naked guy. Don't look down, don't look down!!
When this album was released there was a big ad for it in Rolling Stone. The ad was the full album cover picture as shown here but there was a slight addition. On the thighs of the woman were head shots of The Beatles.. This wasn't a matter of seeing something that may or may be there. The faces were quite obvious.
This is debatable given the modular data of the cover, but since it was mostly sold in a cardboard like foldable CD cover…
