Dot Dot Dash: National Library of Wales communication exhibition
An exhibition is charting the past century of communication, from the first broadcast in Wales to early cartoon satire.
The National Library of Wales' guide down media memory lane in Aberystwyth delves into the National Screen and Sound Archive of Wales' collections.
Dot Dot Dash: Communicating in Wales has early radio and TV sets on display, home movie clips and radio broadcasts.
It started on Saturday and runs until 14 September 2013.
Dot Dot Dash traces some of the big developments in communication from the rise of the telephone in the 1920s and the first broadcast in Wales in 1923 to the digital age of the internet.
Among the radio clips is Neville Chamberlain's radio broadcast in 1939 telling Britain that the country is at war with Germany.
It also looks at BBC Radio Cymru's first broadcast in 1977 and the advent of the Welsh language TV channel S4C 30 years ago.
The exhibition has also borrowed objects from the Museum of Communication in Fife, Scotland.
Jaimie Thomas, exhibitions officer at the national library, said: "We are delighted to show off the collection of the National Screen and Sound Archive of Wales in this exhibition as we trace the history of communication in Wales between 1912 and 2012."
This exhibition also traces the roots of illustration and cartoons in Wales, and displays works by some of the most notable Welsh cartoonists and illustrators who have created Dr Who, Spider-Man, Batman and Judge Dredd comic strips.
The library's collection of Superted cartoons and some of the earliest satirical work by Welsh cartoonists are also on show.
On 26 January, the library will hold animation workshops, guided tours, as well as showing various films from The National Screen and Sound Archive of Wales collection.
