Marketing material needs to be made with a specific purpose in mind. So
before you create something, you need to ask yourself who the audience
is and who will carry it to that audience.
Likely audiences in the near term are guest at expositions and
conferences. Flyers (to pass out) and posters (to decorate) are the
obvious types of material for these occasions. So talk to the people
who are going to staff these events to see what they need.
Alternatively, and additionally, devise other scenarios where printed
matter or brochures could be used. I can't think of any right now, but
maybe you can.
