During the 1920s and 1930s, the Welsh language was in severe crisis. This led to Ifan ab Owen Edwards founding Urdd Gobaith Cymru in 1922, which organised summer camps for younger people. Within 10 years, it had 50,000 members.
In groups, students could design a poster to attract Welsh children to holiday at a Welsh youth camp, including details of the various types of activities they could expect to enjoy. They could then write a postcard from a modern day Urdd camp describing their experiences.
