While I was working on the major overhaul of Rosanna, I mentioned that if the layout was subpar I would rework the map into a detail map or main menu background.
The layout was subpar.
To use this as a background map, go to the autoexec.cfg file in your "Team Fortress 2/tf/cfg" folder (or, if you don't have one, use the pre-included autoexec.cfg) and include the line "map_background background_rosanna_v1". Launch your game, and bam! There it is!
