Large collection of gaffed card sets.

This is an old plastic wallet with 30 sets of special cards each for a particular effect. Each set is clearly labelled. To pick a few at random: 'Faulty Flowers' 'Assassination', Hallworth's Colour Change', 'Tipsy Card', '13 of Clubs' etc. 

This looks to be the resource of a working magician some time ago and came with a collection of books I acquired some time ago.
