Josef Tari is a Hungarian gentleman whom began his collection of miniature books in 1972. His library of petite reads – the smallest book being only 2.9 x 3.2 millimeters and some over 100 years old – has grown to over 5000. These darling little novelties arrived about the year 1475 and remained a popular item throughout history – until about the 1970’s.
Josef is a printer by trade, which is what first attracted him to the little books. Most of the miniatures are Hungarian, but Josef states “I have several books in other languages. I have books e.g. from Canada, Mexico, the USA, Australia, Indonesia and Japan, and from almost all European countries.” – and has 400 books he is willing to exchange. Josef has also published his own mini books seen here.
Now, for the collection.
