Putting An Ad In The Header Next To My Logo (MH Magazine Theme)

I am trying to put an ad or image (728×90) in my header next to my logo. Their is no widget for this area to put it in so I am kinda lost. I have been messing around with the CSS and HTML a little bit in a child theme but I cant seem to figure it out. I am using the MH Magazine theme.

My site is: https://hiphopfanatix.com/ if that helps.

Any help is appreciated.
Thanks
