Meeples for the board game “Wonderland's War”. (Standard size meeple included in the photo for comparison purposes.) The picture shows a Queen's soldier with their spear, modeled after their original prototype. I've since removed it, and added Queen_v2, with the spear more vertical - to match the sticker.
If someone wants to share with me some clear, shot-from-the-front stickers with a size in mm, I'd be happy to come back and revisit this.
