Here is what David had to say about this box set:
"The "Pride of Lions" Box Set includes some of the most sought after, extremely rare decks from David's personal collection. The "Stealth Deck" is full of great secrets and at least 48 gaffed cards.
No instructions included!
Only magicians please. Secrets not to be shared.
All red db brick boxes have been autographed by David."
