Interesting (I think). I remember the problem in getting a photo of the hand holding the card under the table. Line drawings are, many times, much, much, easier. We (the photographer and I) tried all kinds of angles - I remember both of us lying on the floor! Trying to get the lights down there, and etc. What we finally did was - we put a bit of wax on the tip of my thumb, right on the thumbnail, stuck the card onto that and took the picture - no table involved. Then, you took it from there, Andrew. What you did, I have no idea, but it sure depicts what I wanted to depict in teaching the effect.
I'm going to have the same problems with THE CLASSIC COLLECTION, VOL. 2 (if and when I decide to publish). I'm just about starting to re-write The Memory Magic Square out of REPUTATION-MAKERS. O'boy! Getting photos of those charts/squares,with handwriting, etc., is going to be fun! HARRY LORAYNE.
