From John Fisher's auction, lot 42.
Small booklet on contact mind readin (Hellstromism) with a number of experiments, some classic ones, and a list of "do and don't" quite interesting. One of the points is not to indulge in alchool before a demonstration, as this deadens the sensibility to the impulses... quite obvious.
In fairly good condition, with some shelf wear. It would be benefit from being stored in an envelope.
