Copperfield did a few close-up effects in each one of his television specials. See if you can find some of his television specials on tape/DVD. I don't think they are available for purchase from ABC or David Copperfield; but you may find someone who has them all on VHS, (copied to DVD), because they recorded them each year.
He made a napkin rose, (out of flash paper), floated it, lit it on fire; producing a real rose presumably from the flames, (a la, Kevin James).
He did a ring flight once where the ring ended up tied in the laces of a little shoe in his back pocket. Corny - but his handling of it was not bad considering what he had to work with.
He did Jay Sankey's "Air Tight" once.
He actually vanished a yellow silk once. Used a FT instead of a TT; but he actually did the old standard on national television!
He produced pearls from 'nowhere' on the one where he walked through the Great Wall of China.
He also did a Torn & Restored thread on that show.
He did a bill switch - from a borrowed $100 to a $1 - and back again. With a TT, and on a close-up shot on national television to boot.
He did "Misled," a pencil through a borrowed bill illusion that's stronger than any pen through bill effect so many of us do these days.
He did the Card-Thru-Window with Jane Seymour on a moving train. ...Is that considered 'close-up'?
He did another ring flight - I think before the little shoe one - where the ring showed up on one of those old-fashioned key ring/wallet things which no one has used since 1975 and that are only available now when purchasing a ring flight!
He did another illusion - I don't know its name - where a spectator drew a geometric shape on a pad. David then put a few drops of ink in an aluminum pie pan. The ink moved around until it snapped into the shape drawn by the spectator.
He did the Cigarette Thru Quarter illusion long before David Blaine or Criss Angel, (using a quarter borrowed from an audience member that just happened to be his real-life father - though he never told anyone else that was the case).
...Those are just the close-up ones I can pull off the top of my head that David Copperfield has done on national television. There are surely more I'm missing; but I think it answers the question as to whether or not he does close-up illusions!
Very nice post. Funny how nobody else (including me) knew that he did all of these. On a side note, I will be picking up 'Airtight' in the next month or so. Anyone know what it's like?
