Mr. Metcalf was selling these at his art booth at the 2014 NTRPG convention.
They were priced at $5 each and he signed them if you wanted.
There were not very many copies printed, though I do not know the exact number.
When I looked at the link provided above there were only 6 copies remaining. (5:30 AM Saturday 6-14-2014)

Swindle is a trading village that was abandoned by humans and repurposed (taken over) by Goblins and the town is located near the city of Whisper.
Humans and humanoids trade with them for liquor and other vices.
