As I mentioned in a reply to one of the comments made last time, finding figures of Wild West female townsfolk is hard but finding figures of children for this genre is even harder. Fortunately, I do have some. Here's a sample of some of them.
I'm currently painting a couple of child heroes for the Shadows of Brimstone game - male and female orphans, and they are superb sculpts. Not all children need be innocent bystanders. I strongly approve of Flying Frog's decision to include children as hero characters in their Weird West game. I'm planning on buying the two Wild West children figures from Reaper's excellent Chronoscope range next month, so expect to see some armed children here soon.
