For many people sending a postcard is an enjoyable part of any seaside trip but rather than just being a novelty they were once a vital form of communication and often the quickest way to contact your friends and relatives. Dan is joined by Chris Taft and Georgina Tomlinson from the postal museum where a new exhibition marking 151 years of the British postcard is being launched (it was meant to be the 150th exhibition last year!). Chris and Georgina talk us through the surprising history of postcards from their inception and rise to prominence, to the coded messages sometimes contained on them and the link home they provided not just for holidaymakers but for soldiers on the frontlines as well.
