Free tool
Tour date maker.
Type one show per line, pick a look and the sizes you need, and download see-through PNGs to drop onto your poster art. It all runs in your browser: nothing is uploaded.
Want it to fill in by itself?
In BNDMNGR you tick the shows and the date files make themselves from your calendar, for one show or the whole tour, and update when a date changes.
