Manchester & Salford promotional postcards, 2021's stating "spread the word but not the virus," with a note calling for attendees to mask up, test, or just no-show if they were unwell; 2022's postcard calling on us to just "spread the word," but still has a note asking attendees to mask up if they can and, again, no-show if feeling unwell; 2023's postcard simply says "spread the word," and that's it.
