Pretty straight I guess
my idea is to briefly discuss here what should be the technical side of it (maximum size and file dimension basically, format) and leave the creative part completely in the hands of our artists, putting up a competition to decide (a very simple poll with option, nothing really different from what we are used to here).
I'm not techy, but from my previous experience anything in PNG format with something like 350*700 pix and max size of 500KB should work.
Logo is really optional and should be consistent in style and colors with the banner, so maybe if we really want it we can ask the winning artist to make it after their winning banner. Alternatively, or in addition, we can also ask for a signature bar.
ps if you are wondering what use we could do of a banner/logo/sigbar, then there are various possibilities: promoting the Curia in our signatures, adding a bling to the most important curial threads (constitution, reports), in the Curia CMS and in general every time we wanted to identify something so that it is promptly connected with the Curia.
