Joseph Boyer from Paris, France, wrote in the 1950's three books on chess variants, called:
These books, written in French, describe many chess variants. I bought a copy of the second book from the bookshop of the Nederlandse Bond van Schaakprobleemvrienden, and am at the lookout for the other two. The book I bought contained the signature of Boyer.
The books were published by the author. The first book costed 300 francs. Both the first and the second book contained 100 pages, and 50 or 49 chapters. Several diagrams illustrated the games.
