This was the Esperanto Association of Britain's site from 2005 to 2018. You will find its current site at esperanto.org.uk.
Since the 1960's Peter has contributed drawings, artwork and cover designs to a wide variety of EAB's and other Esperanto publications, and generations of Esperanto students will be familiar with his work. Below is just a sample, from the "Jen Nia Mondo" course (1975), "La Graveco de la fideliĝo" book, VHS and DVD (1987), the Elementary,..! Esperanto course" (2003), cover-designs for the recently-published "Mini" series of pocket books, and logos for the "Springboard to Languages" programme raising language awareness in primary schools.
