As a general rule, you only have a few seconds
to grab the attention of your target audience and keep it. In just the
few seconds that they happen to pass by your posters, make sure that
they would stop and read more of what you have to say.
Always remember that your posters or any other sales literature and
print advertising tools must always be posted and distributed on public
places. In addition, in order for them to create a ruckus, you need to
give them a reason to read your message.
