This idea for this book is old! I have just not got round to making it. Last year TICTAC (on request) sent a variety of artists postcards which form the samples for this book, with Book 2 containing various examples received as Mail Art. From my reading, Austria was the first country to publish the postcard, although it was not their invention. A few years prior, German postal official Dr Heinrich von Stephan submitted a proposition for such an item – it was hotly debated and did not appear until July 1870, a year after Austria. Within two years, the postcard had quickly spread across Europe with the USA issuing postcards in 1873. (information available online – The History of Postcards, Smithsonian Digital Library.
