The Liechtenstein Study Group was organized in 1984 and ran into 2015. The group’s original membership was drawn from the American Helvetia Philatelic Society, American Philatelic Society, the British & German Liechtenstein societies, as well as some dealer lists.
Access to the group’s publications and Liechtenstein-related covers is made possible through the efforts of Paul Tremaine who can be reached via e-mail here.
