I sport all 7 volumes of the Mind Mysteries series and it is fantastic. 90% of the DVDs material is strong mentalism (Mind reading, metal bending, mentalism with cards, stopping watches, etc.) It's basically like owning The 13 Steps to Mentalism in DVD format. The other 10% is his renditions of classic effects that are unbelievable, (Signed Quarter in bottle, Card in Cigarette, an unbelievable signed torn and restored newspaper, only to name a few)
Richard Osterlind's teaching is top-notch and the real value of the series is to study how he interacts with his audience and his stagecraft.
