## Transposition

Roxy

### Effect

Two packs of cards, one with red backs and the other with blue, are introduced and spread, face upwards across the table. Two spectators are asked to remove a card, one from each pack. The cards are signed and returned to their respective packs.

Without any "moves" the two packs are spread out, face upwards. They are then flipped over, so that they are face down. In the centre of each pack is seen a single card of the opposite colour. These are removed and seen to be the signed ones.

### Set Up

Two packs of cards will be needed. They should be of similar design but contrasting colours. Usually these will be red and blue. Ensure that both packs are in a similar state of newness, so that, when face up, they are indistinguishable from one another.

The packs should be set up as follows:—

a) The blue pack. This is shown in fig 1. A is a Blue backed Four of Spades.

B is a Red backed Two of Spades. C is a Blue backed Two of Spades. D is a Blue backed Five of Clubs.

Cards C and D occupy the 9th & 10th positions from top.

b) The red pack. This is shown in fig 2. E is a Red backed Five of Clubs.

F is a Blue backed Ace of Hearts. G is a Red backed Ace of Hearts. H is a Red backed Four of Spades.

Cards G and H occupy the 9th & 10th positions from the top.

Once the working of the trick is understood, the actual values of the cards can be varied. It is important, however, that card A and its duplicate H be easily confused with card E and its duplicate D. In other words they should be the same colour and of similar value. For instance, if card A were a red spot card (7) then E should be a red spot card of similar value (6H or 8H). The value of B (and its duplicate C) and F (with its duplicate G) are not important.

Nor for that matter is it essential that C&D and G&H are exactly 9th & 10th from top. All that matters, is that they are somewhere where they can be kept under control and out of the way during the trick. Indeed, they could be removed altogether, if desired. To do so, however, would leave the packs incomplete for other tricks. In the 9th & 10th positions, they are near enough to the top to be retained during a casual shuffle.

Put the packs into their respective case. Also have a packet of peelable adhesive stickers .handy.

### Working

Bring out the two packs, in their cases. Remove the red pack and spread it, face down, across the table, keeping the top few cards bunched so as to prevent the odd blue backed one from showing.

Do exactly the same thing with the blue pack. Flip the red pack face upwards and do like wise with the blue.

Invite a spectator to withdraw a card from the red pack and have another do the same thing with the blue. Ensure that they take the cards from anywhere, other than the stacks. This is fairly easy to do. Simply adjust the spreads, making them wider in the cehtre and more tightly bunched at the inner ends. This will merely give the impression that you are widening the spread to allow a better choice. Also, when you invite them to choose a card, casually point towards the centre of each spread.

FIG* 2

Bring out the adhesive stickers and stick them one onto each chosen card. Have the spectators sign them. While they are doing so, gather up the red pack and casually shuffle it, face towards the audience. Finally square it, face upwards and double cut card E (The Five of Clubs) to the face. Lay this alongside the other pack as in fig 4.

Because of the similarity of the face cards of the two packs and also the fact that attention has been focused upon the two spectators, signing their cards, nobody will know for sure, which pack is which. Each pack has a card of the opposite colour, face up on the bottom.

Pick up the pack with the Five of Clubs on the face. Turn it face down. It will appear to be the blue backed pack. Insert the blue backed chosen card face down into the centre and table the pack. Turn over the other pack and insert the red backed chosen card into it.

Spread both packs, face upwards across the table. Then, so that people know which pack is which, turn the two top cards face down as in fig 5. Pause for a moment and go through whatever presentational mumbo jumbo pleases you.

Finally, pick up the face down red indicator card and use it to flip its entire spread face down. All of the cards will be seen to have blue backs, apart from one in the centre. Do the same thing with the blue indicator card and its pack. Withdraw the odd cards from the centres of their respective packs and show that they are the chosen ones.

Everything is now clean.

### Editorial Note

There is little that is new in this effect but I was greatly impressed with the way, in which Roxy has eliminated all of the sleights and reduced the whole thing to an almost self working trick. It is an object lesson in how, with a little thought, a few subtleties can obtain results far in excess of those achieved by many combinations of elaborate moves.
