Peter Reveen was quite popular as a stage hypnotist in my neck of the woods when I was a younger man.
He also performed magic tricks and feats involving memorizing a deck of cards onstage. I just came across a video from 1979 of him doing a card memorization feat.
Peter Reveen died a few years ago, but his son Tyson (Ty) has continued the show. I believe he also performs a card memorization feat, possibly the same routine.
I know that many people on this site would have no problem replicating this feat, but I found it fun to watch just the same.
