In the premier issue of a new magazine I saw today, the first line reads "Welcome to premier issue of Whatever Magazine!"

I was thrown by the lack of some other word preceding "premier". It could have an article like "the" for "the premier issue", or it could have also said "our", as in "our premier issue".

So is the sentence, as it stands, correct and simply an esoteric usage of grammar? Or is it an actual error?

In an answer below, a rule about not using the article before the name of a city is brought up. However, I'm not sure this applies as "Vegas/Rated" is a proper noun, and the name of a magazine, regardless of a portion of it being a city name.
