It does look good, but it's not exactly a Newark style Italian Hot Dog. This sandwich features beef dogs; the one here seems like it has spicy sausages. The potatoes are sliced or in chunks; not french fries. Onions (though I exclude them) are also different. The pizza bread has a weird yellow color.
The closest thing I've seen to an Italian Hot Dog outside of Jersey is this place in the Bronx: http://www.roadfood.com/Forums/Italian-Hot-Dogs-coming-to-the-Bronx-m483234.aspx
Only thing that keeps it from 100% authenticity is that the dogs are boiled rather than fried.
