100 Latvian Letters is a book that serves as a small insight into the Latvian design heritage, as a collection of observations made in the search for "Latvianness" in the art of letters. The book contains 100 samples of letters from various sources from 1890 to the 1970s. One of the goals of this book is to examine how exactly the letters that Latvian Latvians saw daily in newspapers, magazines, advertisements, and packages had changed. What letters did Latvians have in their wallets, mailboxes, kitchens, and bookshelves?
