That would be my take on it.   It's contains a relative clause with no subordinator.  Because the sentence sounds as if it comes from an ad, it uses the sort of elliptical language common to ads and leaves out, as you point out, "It is" or "This is."

Subject: Independent clause or noun phrase

Happy holidays all. 

I've been a member of this listserve for years and occasionally seek your collective opinion. Question: how does one parse the following?:

The last grill brush you will ever need.

I could see this as an independent clause, with "you" as the subj. and "The last grill brush" as the DO, but that doesn't seem right. Seems there is an implied "It is," making the above a noun phrase, and therefore not an independent clause. Thoughts?

Thank you, 

Scott Lavitt
