There's a little bit more to it than that. While some of the variations are due to the front border, some are only due to the text write-ups on the back. When comparing the backs you'll notice that some have text on a differing numbering of lines (i.e., one version may have 3 lines of text another may have 4, but the words are the same). Or, if the line numbers are the same, the length may be different. After all the VARS were updated I went back and had 2 tabs open so I could compare side-by-side when entering.
Tired and trembling
I am descending,
will I have to stay here
and live this life again?
