Here's an image from the Baje Nalozki Sagen Brauchtum (Book of Woodcut Artwork), courtesy of the image gallery at the Texas Wendish Museum. (The gallery is an autoplaying slide show, so I regret I cannot link directly to the source image.)

I'm not exactly sure what's going on here, but I'm sure there's a story behind it.

Caption ideas (even NSFW-ish ones, if they're funny) are welcome in the comments.
