Damn, I completely ignored the fact that you were using i3. Damn. xD
No problem, I have all logos so I can change it in 2 minutes, my bad.
I can remove or replace the motto, but I think Manjaro Linux has to be there, after all, these are Manjaro promotion wallpapers (I had the dream that manteiners would include these in their ISOS :’( ).
I could chage the motto by the original I posted, " I3-TWM Community Edition". That would keep you from explaining anything when you post a screenshot. :v
