Invision Harvey Raft - Trick

While the performer's back is turned, a volunteer is asked to circle an image of a playing card (from 52 different card images) on a laminated, 2-sided 8.5 x 11 inch card - the volunteer then places it into an opaque envelope (still while the performer's back is turned). The performer divines the image.

The performer is 100% correct!
