With 'Blood Red for Sale' we start a series of connections with misterious simmetrical allignments, but first, before getting into those, we can see that both album covers have a very similar orange color palette with difused camera lens takes, and it might even seem that the orange from Under a Blood Red Sky is spilling into Beatles for Sale. And see those vertical lines dividing the covers (the basis of the geometrical alligments). In The Beatles for Sale it is a tree behind The Beatles, while in Under a Blood Red Sky it is the mic stand. Geometrically they divide the whole covers in two. And amazingly they both even have some kind of hook at the top (see arrows). But the positioning of the vertical lines is even more misterious when we consider that the distance between them and the exterior sides of the cover is pretty much exactly the same in both albums allowing for some very interesting allignments that you will see when you play the video below!
