Playing Cards (The Fournier Museum catalogue)
subtitle: General History From Their Creation to the Present Day
by Felix Alfaro Fournier
This is a multi-volume catalogue of international playing cards from the large collection of the Fournier Playing Cards Museum in Alava, Spain. This collection includes the De La Rue collection so there are many British cards. Volumes one and two are available in English, as a box set or separately. The first volume has 4,000 colour pictures with brief write-ups on 2,000 decks. There are some errors in the information given so it is best to confirm with other sources. The first volume was published in 1982, with 344 pages. The second volume is much slimmer and was published in 1988 to catalogue the cards added to the collection since the first volume was written. Same goes for all subsequent volumes, but they are only available in Spanish, if you can find them at all.
