Here is a poster I made for the Dead Boarder scenario. The map and photos are from 1930s Rhode Island where the scenario is set. Both the final version and a template for you to add your own text to are attached. I did not end up using the poster because the group filled up fast. I did use the smaller version on Facebook. If you'd like the PSD for either let me know.
Also there's a small flyer I made (CoC Flyer Distribute.odt). I printed a bunch but ended up filling the group before I passed them out.
If you use any of these, I'd like to hear about it!
