Sounds like fun.
Additional details from the folks at the Museum:
The books will be available for purchase through The Museum Store, but the event will take place inside the magnificent Sam Noble Special Events Center. Guests are encouraged to make a full evening of their visit by making dinner reservations at the Museum restaurant, Dining on Persimmon Hill. Reservations for the special evening buffet are requested and can be made by calling (405) 478-2250, Ext. 281. (Buffet must be purchased separately.)
Books may be pre-purchased through The Museum Store by calling (405) 478-2250, Ext. 268. I think you can get books at the event also.
