This is from a Private Estate in Good Condition. This is a staplebound booklet that has some fading around the edges on the front and back covers. There is a small stain on the bottom left of the front cover.

This is not just a trick. It is a complete card act that can last about 10 minutes before finishing with an unexpected color-change of the whole deck. 

Many of the color-changing deck effects have to be used as openers. I thought that the color-change would appear more like "real magic" if it came at the end of the card act. 

This is how COLORFULLY AMBITIOUS came about.
