It is never too early to start building a library and to have a bookplate of one's own. The Australian artist GD Perrottet (1890-1971) was commissioned to design this for Princess Elizabeth, later Queen Elizabeth II. It was a gift to go with 'Y Bwthyn Bach' or 'The Little House', the child-size (two-fifths scale) whitewashed thatched cottage in the grounds of the Royal Lodge in Windsor which was presented to the Princesses Elizabeth and Margaret by the people of Wales on Elizabeth's sixth birthday.
