With Urdd Gobaith Cymru (the Welsh League of Youth) celebrating its centenary in 2022, this volume brings the loveable character Mistar Urdd to life within one volume. It comprises three cartoon stories in graphic style - 'Mistar Urdd a'r Allwedd Goll', 'Mistar Urdd yn Llangrannog' and 'Mistar Urdd yng Nglan Llyn'. A colourful book for children of all ages!
