Prof. Marvel's Crystal Ball app analytics for January 16

Professor Marvel was a traveling magician. He studied with many of the best ghost talkers of the time. Your iDevice shows a beautiful transparent crystal ball on a draped table. You show one spectator a group of magic posters from the golden age of spiritualism: Alexander, Fay, Thurston, Carter, and Houdini. One spectator selects a poster and keeps his selection to himself. The other spectator rubs the crystal ball and the selected poster comes into view! Download the posters at our support page for free! A Fun routine for all ages and skills.
