In the late 1920s and early 1930s there were around one quarter of a million practising Spiritualists and some two thousand Spiritualist societies in the UK in addition to flourishing microcultures of platform mediumship and 'home circles'. Spiritualism continues to be practiced, primarily through various denominational spiritualist churches in the United States, Canada, Australia and the United Kingdom. In the United Kingdom, over 340 spiritualist churches and centres open their doors to the public and free demonstrations of mediumship are regularly performed.
In 1960, psychic investigator Andrija Puharich and Tom O'Neill, publisher of the Spiritualist magazine Psychic Observer, arranged to film two seances at Camp Chesterfield, Indiana using infrared film, intending to procure scientific proof of spirit materializations. The medium was shown the camera beforehand, and was aware that she was being filmed. However, the film revealed obvious fraud on the part of the medium and her cabinet assistant. The exposé was published in the 10 July 1960 issue of the Psychic Observer.:96–97
The first documented tarot packs were recorded between 1440 and 1450 in Milan, Ferrara, Florence and Bologna when additional trump cards with allegorical illustrations were added to the common four-suit pack. These new decks were called carte da trionfi, triumph cards, and the additional cards known simply as trionfi, which became "trumps" in English. The earliest documentation of trionfi is found in a written statement in the court records of Florence, in 1440, regarding the transfer of two decks to Sigismondo Pandolfo Malatesta.
