No, I'm not wrong. I'm ex-Mennonite with Amish family. Their dolls do not have blank faces. Maybe the extreme white toppers, but not the conventional black toppers. You're right that they're biblical literalists though.

Not true. They just don't like to be photographed going about their daily lives -- especially when it's a photo of a child. It happens to them multiple times whenever they go in public, especially in the summer / tourist season.
