The Worker's Diary by David Forrest

With The Worker's Diary by David Forrest, a spectator finds the playing card assigned to their birthday—and that card proves to be the only red card in a blue deck, with “Happy Birthday” written on its back. They can also check another date and see it leads to a different card, adding an extra moment of conviction to this birthday card magic effect.

Mark Elsdon’s effect is designed for performance: the routine is self-working, and the compact souvenir-style diary takes up very little pocket space. You can also access the specially compiled Google Diary on your phone instead of carrying a physical diary.

• Birthday card reveal: A date in the diary identifies the spectator’s birthday card.
• Distinctive card finish: Their card is the only red card in a blue deck and has “Happy Birthday” on its back.
• Self-working: The effect is described as self-working, making the routine straightforward to perform.
• Special deck included: The release comes with a special deck for the effect.
• Diary options: Use the small souvenir-style diary or access the Google Diary on your phone.

It’s a personal, memorable reveal to bring to birthday gatherings, where the spectator’s own date becomes the focus of the magic.
