Header removal

To finish up a very simple form based page …
Can anyone tell me how I can remove the upper frame and down arrow?
It’s probably meant for a menu, but, I am not needing a menu.
I do not see a theme built-in mechanism to remove the top of the page>
I’d like the to to begin with the image and not the blank space above.
Hope that’s somewhat clear.

Thanks
