I received an email today that said:
Thank you for joining us
We hope you enjoyed the show.
Then it goes on to say to hurry because the offers expire April 10. No mention of the lithograph.
As a side note I had trouble with the webcast also. When the count down clock hit zero nothing. I think I refreshed and it played fine after that but I missed the first minute or so. My kids watched it with me and we enoyed the webcast. I thought it was much better than the last one.
