When many of us think of banners in church we have this freak image of the tacky "hippie" banners we used to see in our home parishes back when we were kids.
But this is how it's done in Rome, or was more commonly seen in Rome. The extras count and they take a little extra work. This is where archconfraternities come into play as well as (authentic) lay participation.
These are "requiem" banners and they were put up in the sanctuary for All Souls Day at the Rome FSSP parish, Santissima Trinita' dei Pellegrini.
