I purchased this as a hardcover book when it was first released, after seeing Aldo perform two Oil & Water routines from it.
I really like this book for two reasons: First, nothing is left out. If a routine calls for a move or sleight, it is taught, and never leaves you running to other resources to learn it. If you look at the table of contents listed here on Lybrary.com, you will see how "full" this book is with sleights and variations. Second, the routines taught in here are not difficult at all, but have a strong impact from a visual and "astonishment" perspective.
The two O&W routines I refer to are "Nice Salad" and "Italian Dressing". One uses just 8 cards, and is very visual. The second uses a 9th (hidden) card, but allows even more visual astonishment.
$10.00 is a steal of a price for the amount of material contained in this book.
So, oddly enough, two of my favorite books on card magic have bright yellow covers: "What's Up Deck?" by Aldo Colombini, and Richard Kaufman's book on Bro. John Hamman's card work.
