Guerilla Marketing in Local Colleges and Universities

I plan on displaying the banner in local Colleges and Universities to promote STEEMit to students trying to make their way in this world.
I am purchasing blank card stock and a second stamp to pass out business cards at events and to the general public.
I bought the stamp a while ago and use it while I work to stamp customer receipts. I have currently stamped around 500+ so far.

I can also place the banner in other locations in hopes to bring new users to the platform. Also I can place it at libraries, 5k's, Carnivals, Fairs, Parks and many other creative spaces to attract creators to the platform.
