So I sent to Jen via OUAT twice (once with money for postage, once with stamps because I figured that was why she hadn't responded) and received successes both times, so I have an extra signed 4x6 from her for no reason.
I'd like basically anyone else from Once Upon a Time (other than those listed on my signature), but especially an authentic Ginny or Lana, since they both use autopen now. Obviously a 4x6 photo isn't worth much, so if you've got an authentic auto on something more valuable, I'd pay for the difference.
