No, the yf-19 arts are printed inside the 1/100 vf-19 box, that are the instructions.
I don't know why the yf-19 arts are printed inside the box, maybe as reference for who wat to costumize the vf-19 in a yf-19 or is just an extra.
There are also the normal battroid and fighter artworks, fighter top view and side view and some text in japanese about the yf-19, nice stuff.
