Early Access or Bonus Material (Patreon)

In future, would you all prefer things like the Celestia pinup poster to remain Patron-exclusive bonus material, or would you like to see them released publicly after one month?

I'm not a huge fan of paywalls, but if it means more patrons and more money, then I can justify spending more time making content, so I figured I'd throw the question out to those of you who already support me
