With the introduction of the railway, Devon became a popular holiday resort in Victorian and Edwardian times. From 1894, picture postcards were first produced and were sent in their thousands.With several deliveries a day, a postcard could be sent in the morning and received in the afternoon. Because of this, thousands of images of Devon were produced and many survive to this day to be found in second-hand shops and auction rooms.Devon also includes the vast expanse of Dartmoor, made famous in the Sherlock Holmes novels of Arthur Conan Doyle. Many once popular holiday destinations now look worse for wear. Gone are the trams, the pleasure cruises and the many tea rooms that catered for visitors in the early 1900s. Devon is still a beautiful county which welcomes hundreds of thousands of visitors every year.
