The diary trick has become a classic effect in mentalism and card magic.  This is because it uses a date significant to the audience, such as their birthday or wedding anniversary.

Chris Congreave’s “No Diary, Diary” is a diary trick that uses no actual diary and everything can be carried in the performer’s wallet.

The basic effect is that the performer brings out a small laminated calendar-type card that has a playing card printed in each day of the month.  A spectator names her birthday and finds her “lucky card” printed on her birth-date.  The performer brings out his wallet, and inside the wallet is a playing card that matches exactly the spectator’s “lucky card”!

You are supplied with the laminated calendar card, and a printed booklet of instructions.  The instructions provide several presentations, including a comical sucker effect and a stage version that involves 5 members of the audience.  No memory work, instant reset, almost self-working, and works with any date!  (4.5/5 stars rating.)
