There's a new poster map design up on Kickstarter, but before I post the link I want to add a disclaimer here that it's not my map, and I'm not directly affiliated with the creator. It's also not specifically for SWM, though the dimensions are close and it might be OK for a casual game. He did approach me about doing some work for his company, but thus far I haven't had the time to commit to it.

The price point is higher than we're used to for a printed map, though a 5$ pledge will get it in PDF. Anyway, just posting this here as a point of possible interest.

Based on feedback, the creator has added a lower price point to get the poster and made it double-sided. He has also updated the artwork.

Click on the "updates" tab on his kickstarter page to get a look at the improved details or an in-progress look at the other side:

Again: this is not an endorsement; I'm just passing along updated information.
