Has anyone ever seen these? Nike Sb Dunk Chicago EMB Brazil exclusives

These are Nike Sb Dunk EMB Brazil exclusives in a Chicago colorway but ive never seen these before. Ive only seen the ones with basically the same colorway but just with black lines all over them. Ive owned a tew pairs of embs before except ive just never seen these on the market so ive no clue what they really are. Just to give context these are Size 6 in mens, could this colorway be exclusive to gs? Here are some photos. Colorway on box says black varsity red. Does anyone know the name?
