The leather-bound work, with dimensions of 5 km. for 5 km. – less than the tip of a pencil – contains versions of the Sunday Prayer in Dutch, English (British and American), French, German, Spanish and Swedish.
Its price was estimated at between 1,000 and 1,500 euros, but an anonymous buyer acquired it at the Arenberg Auctions auction in Brussels for 3,500 euros and paid 4,200 euros at an additional cost.
“The printed text is so tiny you can’t read it with the naked eye, but you need a powerful magnifying glass,” said Henry Gotz, the auctioneer.
The book, entitled The Lord’s Prayer, was one of hundreds published in 1952 by the Gutenberg Museum in Mainz, Germany, as part of a fundraising initiative to rebuild the building after World War II.
It is one of the oldest Printing Museums in the world and was named after Johannes Gutenberg, who pioneered mechanical printing in Europe in the 15th century.
