What do you call the activity of holding {publicity/protest/facts} signs [closed]

What's the word for a place and/or activity where a small number of people stand in the streets with information boards in their hands and inform the passersby people about something (which the information boards are about)?


Solution 1:

If they're trying to spread information about their religion they could be evangelising. If they're trying to bring awareness to an issue (likely political) this cold be a rally. If they're unhappy with an event or ruling this might be a protest.
