In case you haven't bought a calendar for next year, perhaps you could consider the official Witcher 3: Wild Hunt calender from Maul Cosplay. It's a series of cosplay photos, co-created by CD Projekt RED and Maul Cosplay (aka Ben). If you are intersted, you can purchase it for $29. But a warning to you: some of the photos are NSFW.
The calendar inlcudes familiar in-game scenes like Geralt in the bathtub and Geralt and Yennefer on the unicorn.
