Michael Close’s series of manuscripts contain some of the most commercial, entertaining and powerful magic in print, spanning over 20 years of professional performing in real-world conditions. In sharing his work, Michael has held nothing back, including full presentations and extra tips and thinking.

The first book in the Workers series contains two of the strongest routines in all of close-up magic: Dr. Strangetrick and the now legendary Pothole Trick.

Volume One also includes a bit of history about Michael and his philosophy on magic along with tips on audience management in close-up and stand-up situations.
