Marco's Comments:
A collection of routines by Yedid around the principle of two cards rolled together (the audience thinks it's only one) which then changes into another. None of the routines are very good, except the last one, the "bitten deck", which is very practical and good (but it's also a "bonus" routine, having nothing to dow ith the rest).
This is the first edition, a second edition has been reprinted in 2010.
