It’s just a part of her.
All the history buffs out there realized almost immediately that on the cover of Rolling Stone, the signature below the Constituion on Julia's back is wrong.
Because John Hancock didn't sign the Constituition, he signed the Declaration of Independence, DOI!!!!!!!
(You are not alone if you didn't automatically realize this, 8th grade history class was a long time ago, and also there were other things going on this picture).
So Julia used her #tbt wisely, to show that there was no actual mistake made. The John Hancock signature is just PART OF HER.
