Removing the menu bar on full wight page

I thought I was done but I have one more problem. (sigh) Is is at all possible, or let me rephrase that, I know anything is possible but how hard would it be to get rid of my top menu bar on my full-width.php but retain the header image and keep the menu bar on all my other pages?

Or If that is not easy is there a way to nuke the header all together on the full wigth page. I could insert the header image with html if need be. I tried removing the call to header function om full-width.php but I guess it does more than just bring up the header because the page didn’t load at all.
